Antecedentes de la invenciónBackground of the invention
Es conocida una extensa variedad de realizaciones de máquinas destinadas al envasado automático de productos en polvo, sólidos, pastosos, líquidos, etc. en envases en forma de bolsas, obtenidas por conformación de una lámina de material termosoldable. En general, tales máquinas de envasado automático comprenden un dispositivo de conformación de envases y un dispositivo de llenado, enlazados por medio de un dispositivo que transfiere envases desde el dispositivo de conformación al dispositivo de llenado.A wide variety of machine embodiments are intended for automatic packaging of powdered, solid, pasty, liquid products, etc. in bags-shaped containers, obtained by forming a sheet of heat-sealable material. In general, such automatic packaging machines comprise a packaging forming device and a filling device, linked by means of a device that transfers packages from the forming device to the filling device.
En la Fig. 1 aparece representada esquemáticamente una realización de máquina de envasado automático del tipo antes descrito. Esencialmente, la máquina de envasado automático comprende un dispositivo de conformación DC de envases en forma de bolsas, un dispositivo de transferencia DT de envases y un dispositivo de llenado DL, dispuestos longitudinalmente. El dispositivo de conformación DC de envases está compuesto por unos medios de alimentación de una lámina de material termosoldable 1 , unos medios de conformación 2 de envases 3 en continuo en forma de bolsas y unos medios de corte 4 para separar los envases 3 de la lámina conformada en continuo. El dispositivo de transferencia DT de envases 3 comprende unos medios de transporte 5 provistos de unas boquillas de succión para la apertura de los envases 3, para su llenado. Y, el dispositivo de llenado DL está provisto de unos dosificadores 6 y unos medios de cierre 7 de envases 3 llenos. En la Fig. 2 aparece representada otra realización de máquina de envasado automático del tipo descrito. En esta realización, al igual que en la realización representada en la Fig. 1, la máquina de envasado comprende un dispositivo de conformación DC de envases, un dispositivo de transferencia, no representado, y un dispositivo de llenado DL. Esencialmente, el dispositivo de conformación DC de envases no difiere del antes descrito para el modo de realización de la Fig. 1, y elementos similares son designados con iguales referencias numéricas. El dispositivo de llenado DL está dispuesto por encima del dispositivo de conformación DC y comprende un soporte rotativo 8 de con- torno cuadrangular, en el que cada uno de sus lados está provisto de medios de sujeción 9 de envases 3 para su llenado mediante dosificadores 6 dispuestos en uno de sus lados.An embodiment of an automatic packaging machine of the type described above is schematically represented in Fig. 1. Essentially, the automatic packaging machine comprises a bag forming device DC forming device, a container transfer device DT and a filling device DL, arranged longitudinally. The container forming device DC is composed of feeding means of a sheet of heat-sealable material 1, packaging means 2 of continuous packaging 3 in the form of bags and cutting means 4 for separating the containers 3 from the sheet formed in continuous. The transfer device DT of containers 3 comprises transport means 5 provided with suction nozzles for opening the containers 3, for filling. And, the filling device DL is provided with dispensers 6 and closing means 7 of filled containers 3. Another embodiment of the automatic packaging machine of the type described is shown in Fig. 2. In this embodiment, as in the embodiment shown in Fig. 1, the packaging machine comprises a packaging device DC, a transfer device, not shown, and a filling device DL. Essentially, the packaging device DC shaping device does not differ from the one described above for the embodiment of Fig. 1, and similar elements are designated with equal numerical references. The filling device DL is disposed above the forming device DC and comprises a rotary support 8 of quadrangular contour, in which each of its sides is provided with fastening means 9 of packages 3 for filling by means of dispensers 6 arranged on one of its sides.
En general, las realizaciones de máquinas de envasado automático como las descritas tienen como principal inconveniente el que se describe a continuación. Una vez realizado el llenado del envase con el producto a envasar, particularmente en caso de líquidos, el desplazamiento del envase lleno desde los medios de llenado hasta los medios de cierre del envase, provoca que el producto contenido en el envase esté sometido a aceleraciones y des- aceleraciones que causan importantes variaciones del ras del producto respecto del borde del envase, y ello tanto si el envase lleno sigue una trayectoria lineal como una trayectoria circular, lo cual conduce a la necesidad de limitar la velocidad de desplazamiento del envase lleno a fin de evitar el derrame del producto y/o el mojado de la zona donde se produce el cierre del envase lleno mediante soldadura; consiguientemente, tal reducción de velocidad de desplazamiento de los envases llenos previamente a su soldadura conduce a una reducción de producción de la máquina de envasado.In general, embodiments of automatic packaging machines such as those described have the main drawback as described below. Once the container is filled with the product to be packaged, particularly in the case of liquids, the movement of the filled container from the filling means to the closing means of the container causes the product contained in the package to be subject to acceleration and decelerations that cause significant variations in the level of the product with respect to the edge of the container, and whether the full container follows a linear path or a circular path, which leads to the need to limit the speed of movement of the full container in order to avoid spilling the product and / or wetting the area where the full container is closed by welding; consequently, such a reduction in the speed of movement of the containers filled prior to welding leads to a reduction in the production of the packaging machine.

La máquina según la invención se caracteriza porque el dispositivo de transferencia transfiere los envases desde el dispositivo de conformación de envases al dispositivo de llenado mediante un desplazamiento vertical y un desplazamiento horizontal de los envases, realizándose ambos desplazamientos simultánea, alternativa y coplanariamente, y porque el dispositivo de llenado comprende un bastidor en el que está dispuesto un transportador vertical sin fin que describe una trayectoria formada por un tramo ascendente y por un tramo descendente paralelos y enfrentados uno respecto del otro, enlazados por sus extremos correspondientes mediante tramos semicircunfe- renciales, estando el transportador sin fin provisto de uno o más mecanismos de sujeción de envases regularmente distribuidos, desplazables simultáneamente y de modo que cada uno de ellos ocupa sucesiva y secuencialmente el extremo inferior del tramo ascendente, o posición de recepción de envases suministrados por el dispositivo de transferencia, el extremo superior del tramo ascendente, o posición de apertura de envases para su llenado, el extremo superior del tramo descendente, o posición de llenado de envases con el producto a envasar y el extremo inferior del tramo descendente, o posición de cierre mediante soldadura de los envases llenos con el producto a envasar, desde donde son depositados sobre unos medios de evacuación de envases llenos y cerrados.The machine according to the invention is characterized in that the transfer device transfers the containers from the container shaping device to the filling device by means of a vertical displacement and a horizontal displacement of the containers, both displacements being carried out simultaneously, alternately and coplanarly, and because the The filling device comprises a frame on which an endless vertical conveyor is provided that describes a path formed by an ascending section and by a parallel descending section facing each other, linked by their corresponding ends by semi-circumferential sections, being the endless conveyor provided with one or more mechanisms for holding regularly distributed packages, movable simultaneously and so that each of them successively and sequentially occupies the lower end of the ascending section, or receiving position of containers supplied by the di transfer device, the upper end of the ascending section, or opening position of containers for filling, the upper end of the descending section, or filling position of containers with the product to be packaged and the lower end of the descending section, or position of closing by welding of the filled containers with the product to be packaged, from where they are deposited on evacuation means of filled and closed containers.
Las características del dispositivo de transferencia y del dispositivo de llenado descritas aportan una innovadora solución a los problemas derivados del desplazamiento de envases llenos con el producto a envasar, previamente a su cierre por soldadura. En efecto, el hecho de que el desplazamiento de los envases llenos se realice según una trayectoria vertical desde el extremo superior del tramo descendente, donde están dispuestos los medios de llena- do de envases, hasta el extremo inferior del tramo descendente, donde están dispuestos los medios de cierre mediante soldadura de los envases, da como resultado que el nivel del producto en el envase mantenga la horizontalidad, independientemente de la velocidad a la que se realice dicho desplazamiento. De este modo con la máquina de la invención se logra, en primer lugar, evitar el derrame del producto envasado por aceleraciones y desaceleraciones durante el desplazamiento del envase lleno y/o el ensuciamiento de las zonas de soldadura, y en segundo lugar un incremento de producción de la máquina respecto de aquellas realizaciones de máquinas de envasado automático en las que el desplazamiento de envases llenos, previamente a su soldadura, se realiza según una trayectoria rectilínea o curvilínea.The characteristics of the transfer device and the filling device described provide an innovative solution to the problems arising from the movement of full containers with the product to be packaged, prior to closing by welding. Indeed, the fact that the displacement of the filled containers is carried out along a vertical path from the upper end of the descending section, where the means for filling containers are arranged, to the lower end of the descending section, where they are arranged The closing means by welding the containers, results in the level of the product in the package maintaining horizontality, regardless of the speed at which said movement is made. In this way, with the machine of the invention, it is first possible to avoid the spillage of the packaged product by accelerations and decelerations during the movement of the full container and / or the fouling of the welding zones, and secondly an increase in the production of the machine with respect to those embodiments of automatic packaging machines in which the displacement of full containers, prior to welding, is performed according to a straight or curvilinear trajectory.

La caja de pinzas de transferencia 12 también contiene dos ejes horizontales 21, dispuestos entre el par de poleas motrices 14 y 15 y el par de poleas conducidas 16 y 17 y paralelos uno respecto del otro. A los dos ejes horizontales 21 están acopladas cuatro pinzas de transferencia, indicadas con las referencias 22 a 25, con capacidad de desplazamiento en los sentidos A y B. La primera pinza de transferencia 22 está acoplada al ramal superior de la correa de transmisión exterior 18; la segunda pinza de transferencia 23 está dispuesta contigua a la primera 22 y está acoplada al ramal superior de la correa de transmisión interior 19; la tercera pinza de transferencia 24 está dispuesta contigua a la segunda 23 y está acoplada al ramal inferior de la correa de transmisión interior 19; y la cuarta pinza de transferencia 25 está dispuesta contigua a la tercera 24 y está acoplada al ramal inferior de la cinta de transmisión exterior 18.The transfer caliper box 12 also contains two horizontal axes 21, arranged between the pair of drive pulleys 14 and 15 and the pair of driven pulleys 16 and 17 and parallel to each other.

El mecanismo de traslación 13 comprende una leva 26 a la que está acoplado el brazo de potencia 27 de una palanca de primer género 28 en la que el fulcro 29 unido a un punto fijo, en tanto que el brazo resistente 30, que forma un ángulo con el brazo de potencia 27, está acoplado al pie de una biela 31 cuya cabeza está acoplada a la caja de pinzas de transferencia 12; el giro de la leva 26, por medio de un accionamiento no representado, provoca un movimiento giratorio alternativo de la palanca alrededor del flucro 29 y un movimiento de traslación vertical alternativo de la biela 31 y de la caja de pinzas de transferencia 12. El mecanismo de impulsión 20 comprende una palanca de impulsión 32 que por uno de sus extremos está acoplado al par de ruedas motrices 14 y 15, en tanto que su otro extremo está acoplado al pie de una biela 33, estando la cabeza de la biela 33 acoplada a una manivela 34 unida mediante un soporte vertical 35 a un punto fijo 36.The translation mechanism 13 comprises a cam 26 to which the power arm 27 of a first-gen lever 28 is attached in which the fulcrum 29 attached to a fixed point, while the resistant arm 30, which forms an angle with the power arm 27, it is coupled to the foot of a connecting rod 31 whose head is coupled to the transfer caliper housing 12; the rotation of the cam 26, by means of a drive not shown, causes an alternative rotating movement of the lever around the flucro 29 and an alternative vertical translation movement of the connecting rod 31 and the transfer clamp housing 12. The mechanism of drive 20 comprises a drive lever 32 which at one end is coupled to the pair of driving wheels 14 and 15, while its other end is coupled to the foot of a connecting rod 33, the head of the connecting rod 33 being coupled to a crank 34 connected by a vertical support 35 to a fixed point 36.
En la Fig. 5 se aprecia que cada pinza de transferencia comprende un brazo fijo 37 y un brazo móvil 38 horizontales, teniendo el brazo móvil 38 capacidad de desplazamiento en ambos sentidos indicados C y D, estando el extremo interior del brazo móvil 38 unido al brazo resistente 39 de una palanca de primer género 40 cuyo brazo de potencia 41 está acoplado a un cilindro neumático 42; todo ello adaptado de modo que el brazo móvil 38 puede ocupar dos posiciones, una primera de recepción de un envase 3, desde los medios de corte 4 del dispositivo de conformación DC, y una posición de cierre (Fig. 5) en la que el envase 3 es sujetado centradamente por su extremo superior.In Fig. 5 it can be seen that each transfer clamp comprises a fixed arm 37 and a movable arm 38 horizontal, the movable arm 38 being able to move in both directions indicated C and D, the inner end of the movable arm 38 being attached to the sturdy arm 39 of a first-gen lever 40 whose power arm 41 is coupled to a pneumatic cylinder 42; all adapted so that the movable arm 38 can occupy two positions, a first receiving a container 3, from the cutting means 4 of the forming device DC, and a closing position (Fig. 5) in which the container 3 is held centrally by its upper end.
El funcionamiento del dispositivo de transferencia DT se describe seguidamente. En la Fig. 7 se aprecia que el dispositivo de transferencia DT está dispuesto por debajo del dispositivo de llenado DL; la caja de pinzas de transferencia 12 se encuentra en una posición inferior de recepción de envases 3; la pinzas de transferencia 22 a 25, se encuentran en posición de cierre, sujetando cada una de ellas centradamente un correspondiente envase 3 por su extremo superior; y, como se aprecia en la Fig. 4, las pinzas de transferencia 22 a 25 se encuentran dispuestas cada una en su posición más próxima a la contigua, guardando el par de primera y segunda pinzas de transferencia 22 y 23, y el par de tercera y cuarta pinzas de transferencia 24 y 25 una relación de simetría posicional respecto de un eje transversal teórico Y-Y de la caja de pinzas de transferencia 12.The operation of the DT transfer device is described below. In Fig. 7 it can be seen that the DT transfer device it is arranged below the filling device DL; the transfer clamp box 12 is in a lower position for receiving containers 3; the transfer tongs 22 to 25, are in the closed position, each of them centrally holding a corresponding container 3 by its upper end; and, as shown in Fig. 4, the transfer clamps 22 to 25 are each arranged in their closest position to the next one, keeping the pair of first and second transfer clamps 22 and 23, and the pair of third and fourth transfer clamps 24 and 25 a positional symmetry relation to a theoretical transverse axis YY of the transfer clamp box 12.
En estas condiciones, una vez realizada la separación de los envases 3 de la lámina 1 conformada en continuo mediante los medios de corte 4, el giro de la leva 26 da a lugar que, por medio de la palanca de primer género 28 y de la biela 31 , la caja de pinzas de transferencia 12 sea impulsada hacia arriba; las poleas motrices 14 y 15 son giradas por medio de la palanca de impulsión 32 de la biela 33 y de la manivela 34 en un sentido tal que imprime al ramal superior de la correa de transmisión exterior 18 y al ramal superior de la correa de transmisión interior 19 un desplazamiento en el sentido indicado B, y al ramal inferior de la correa de transmisión interior 19 y al ramal inferior de la correa de transmisión exterior 18 un desplazamiento en el sentido indicado A; consiguientemente, el giro de las poleas motrices 14 y 15 durante la elevación de la caja de pinzas de transferencia 12 produce mediante las correas de transmisión 18 y 19 la separación de dos pinzas de transferencia contiguas, al tiempo que la posición de cada par de pinzas de transferencia guarda relación de simetría respecto del eje transversal Y-Y. En la Fig. 6 se aprecia que la caja de pinzas de transferencia 12 ha alcanzado una posición superior de transferencia, ocupando las pinzas de transferencia 22 a 25 una posición en la que los envases 3 son recogidos por el dispositivo de llenado DL. Una vez los envases 3 son recogidos por el dispositivo de llenado DL, el giro de la leva 26 produce el descenso de la caja de pinzas de transferencia 12; el giro de las poleas motrices 14 y 15 en sentido contrario al anterior; los desplazamientos de las correas de transmisión 18 y 19 en sentido contrario al anterior; y el posicionado de las pinzas de tranferencia 22 a 25 detallado en la Fig. 4, dispuestas para la sujeción de otro grupo de envases 3.Under these conditions, once the containers 3 have been separated from the sheet 1 formed continuously by means of the cutting means 4, the rotation of the cam 26 gives rise to the fact that, by means of the first gender lever 28 and the connecting rod 31, the transfer caliper box 12 is driven upwards; the driving pulleys 14 and 15 are rotated by means of the drive lever 32 of the connecting rod 33 and the crank 34 in such a way that it prints to the upper branch of the outer transmission belt 18 and to the upper branch of the transmission belt inner 19 a displacement in the indicated direction B, and to the lower branch of the inner transmission belt 19 and to the lower branch of the outer transmission belt 18 a displacement in the indicated direction A; consequently, the rotation of the driving pulleys 14 and 15 during the lifting of the transfer caliper box 12 produces by means of the transmission belts 18 and 19 the separation of two adjacent transfer calipers, while the position of each pair of calipers of transfer keeps relation of symmetry with respect to the transverse axis YY. In Fig. 6 it can be seen that the transfer clamp box 12 has reached an upper transfer position, the transfer clamps 22 to 25 occupy a position in which the containers 3 are collected by the filling device DL. Once the containers 3 are picked up by the filling device DL, the rotation of the cam 26 causes the transfer of the transfer clamp box 12 to descend; the rotation of drive pulleys 14 and 15 in the opposite direction to the previous one; the displacements of the transmission belts 18 and 19 in the opposite direction to the previous one; and the positioning of the transfer clamps 22 to 25 detailed in the Fig. 4, arranged for holding another group of packages 3.
En las Figs. 7 y 8 se aprecia que el dispositivo de llenado DL comprende un bastidor 43 sobre el que está dispuesto un transportador sin fin 44, compuesto por un tramo ascendente y un tramo descendente paralelos y enfrentados uno respecto del otro, enlazados por sus respectivos extremos mediante tramos semicircunferenciales, sobre el que están montados cuatro mecanismos horizontales de sujeción 56 de envases 3.In Figs. 7 and 8 it can be seen that the filling device DL comprises a frame 43 on which an endless conveyor 44 is arranged, composed of an ascending section and a descending section parallel and facing each other, linked at their respective ends by sections semi-circumferential, on which four horizontal clamping mechanisms 56 of packages 3 are mounted.
En la Fig. 3 se ha representado de forma simplificada el dispositivo de llenado DL apreciándose en el extremo inferior I del tramo ascendente del transportador sin fin 44 la posición de transferencia de envases 3, desde el dispositivo de conformación DC al dispositivo de llenado DL; en el extremo superior II del tramo ascendente la posición de apertura de envases 3 para su llenado, realizándose dicha apertura mediante unas boquillas de succión 48; en el extremo superior III del tramo descendente la posición de llenado de los envases 3 con el producto a envasar, mediante unos dosificadores 49; y en el extremo inferior IV del tramo descendente la posición de cierre de envases 3 llenos, mediante un dispositivo de soldadura 50. Los envases 3 una vez ce- rrados son depositados sobre unos medios de evacuación de envases, consistentes en una cinta transportadora 51.In Fig. 3, the filling device DL is shown in a simplified manner, the position of transfer of containers 3, from the forming device DC to the filling device DL, being appraised at the lower end I of the endless conveyor 44; at the upper end II of the ascending section the opening position of containers 3 for filling, said opening being carried out by means of suction nozzles 48; at the upper end III of the descending section the filling position of the packages 3 with the product to be packaged, by means of dispensers 49; and at the lower end IV of the descending section the closing position of filled containers 3, by means of a welding device 50. Once closed containers 3 are deposited on means for evacuating containers, consisting of a conveyor belt 51.
El bastidor 43 comprende dos ejes horizontales 45 paralelos uno respecto del otro sobre los que pueden ser desplazados en ambos sentidos dos soportes verticales 46, indicados como E y F en la Fig. 8, sobre los que está montado el transportador sin fin 44.The frame 43 comprises two horizontal axes 45 parallel to each other on which two vertical supports 46, indicated as E and F in Fig. 8, can be displaced in both directions, on which the endless conveyor 44 is mounted.
El transportador sin fin 44 comprende un sistema de giro intermitente de 180° 53, provisto de un árbol 47 acoplado a los extremos inferiores de los soportes verticales 46, estando provisto el árbol 47 de dos ruedas dentadas motrices 52 dispuestas entre ambos soportes 46; dos ruedas dentadas conducidas 54 dispuestas en los extremos superiores de los soportes verticales 46, enfrentadamente una respecto de la otra y coplanariamente respecto de ruedas dentadas motrices 52; y una primera y una segunda cadenas de transporte 55 y 58, enlazando cada una de ellas una rueda dentada motriz 52 con su correspondiente rueda dentada conducida 54, estando montados sobre ambas cadenas de transporte 55 y 58 los cuatro mecanismos horizontales de sujeción 56, regularmente distribuidos.The endless conveyor 44 comprises an intermittent rotation system of 180 ° 53, provided with a shaft 47 coupled to the lower ends of the vertical supports 46, the shaft 47 being provided with two driving sprockets 52 arranged between both supports 46; two driven sprockets 54 arranged at the upper ends of the vertical supports 46, facing one another and coplanarly with respect to driving sprockets 52; and a first and a second chains of transport 55 and 58, each linking a driving sprocket 52 with its corresponding driven sprocket 54, the four horizontal clamping mechanisms 56, regularly distributed, being mounted on both transport chains 55 and 58.
En la Fig. 8 se aprecia que cada mecanismo horizontal de sujeción 56 comprende un primer eje horizontal de sujeción 57 acoplado por un extremo a la primera cadena de transporte 55, de modo que ocupa una posición fija respecto de la misma, en tanto que su otro extremo está acoplado a la segunda cadena de transporte 58 transversalmente desplazable respecto de la misma; y un segundo eje horizontal de sujeción 59 situado por encima del primer eje horizontal de sujeción 57, acoplado por uno de sus extremos a la primera cadena de transporte 55 transversalmente desplazable respecto de la misma, en tanto que el otro extremo está acoplado a la segunda cadena de transporte 58 de modo que ocupa una posición fija respecto de ésta.In Fig. 8 it can be seen that each horizontal clamping mechanism 56 comprises a first horizontal clamping axis 57 coupled at one end to the first transport chain 55, so that it occupies a fixed position with respect to it, while its another end is coupled to the second transport chain 58 transversely movable with respect thereto; and a second horizontal clamping axis 59 located above the first horizontal clamping axis 57, coupled at one of its ends to the first transport chain 55 transversely movable with respect thereto, while the other end is coupled to the second transport chain 58 so that it occupies a fixed position with respect to it.
El primer eje horizontal de sujeción 57 está provisto de un primer grupo de pinzas de sujeción compuesto por cuatro pinzas de sujeción 60, dispuestas de modo que la distancia que separa una de ellas de otra que le es contigua es constante, en tanto que el segundo eje horizontal de sujeción 59 está provisto de un segundo grupo de pinzas de sujeción compuesto por cuatro pinzas de sujeción 61 , dispuestas de tal que la distancia que separa una de ellas de otra que le es contigua es constante. Ambos grupos de pinzas de sujeción están dispuestos entre sí de modo que unas pinzas de sujeción 60 del primer grupo de pinzas y la correspondiente pinza de sujeción 61 del segundo grupo de pinzas permiten la sujeción de un envase 3.The first horizontal clamping axis 57 is provided with a first group of clamping clamps composed of four clamping clamps 60, arranged so that the distance that separates one of them from another that is contiguous is constant, while the second horizontal clamping axis 59 is provided with a second group of clamping clamps composed of four clamping clamps 61, arranged such that the distance that separates one of them from another that is contiguous to it is constant. Both groups of clamps are arranged together so that clamps 60 of the first group of clamps and the corresponding clamp 61 of the second group of clamps allow the holding of a container 3.
Los mecanismos horizontales de sujeción de envases 56 antes descritos permiten adaptar la distancia que separa los pares de pinzas de sujeción 60 y 61 de los envases 3 a la amplitud de éste del modo que se explica a continuación. El desplazamiento de los soportes verticales 46 sobre los ejes horizontales 45 del bastidor 43, provoca el desplazamiento de los ejes horizontales de sujeción 57 y 59 de cada uno de los mecanismos horizontales de sujeción 56, al ser éstos solidarios de una respectiva cadena de transporte 55 y 58. Concretamente, el desplazamiento de los soportes verticales 46, aproximándolos entre sí, provoca el alejamiento mutuo de las pinzas de sujeción 60 y 61 de cada par de pinzas de sujeción de un envase 3, en tanto que el desplazamiento de los soportes verticales 46 separándolos entre sí, provoca el acercamiento mutuo de las pinzas de sujeción 60 y 61 de cada par de pinzas de sujeción de un envase 3. The horizontal container clamping mechanisms 56 described above allow the distance between the pairs of clamps 60 and 61 of the containers 3 to be adapted to the breadth of the latter in the manner explained below. The displacement of the vertical supports 46 on the horizontal axes 45 of the frame 43 causes the displacement of the horizontal clamping axes 57 and 59 of each of the horizontal clamping mechanisms 56, as these are integral with a respective transport chain 55 Y 58. Specifically, the displacement of the vertical supports 46, bringing them closer together, causes the mutual detachment of the clamps 60 and 61 from each pair of clamps of a container 3, while the displacement of the vertical supports 46 separating them from each other, it causes the mutual approach of the clamps 60 and 61 of each pair of clamps of a container 3.
