Definitions

  • the present invention relates to a bagging apparatus particularly for granular and/or powdery products and the like.
  • the apparatus is suitable to remove air and/or gas present inside a bag filled with granular and/or powdery product and heat-seal it without the bag reacquiring air or gas from the outside, so as to obtain a vacuum which is adjustable according to the requirements of the product.
  • Packaging usually occurs in bags made of an appropriately selected material, for example laminated polythene or other materials having similar characteristics; these bags are filled completely and closed at the top after vacuum has been produced inside them, so as to minimize space occupation and preserve the characteristics of the product. These bags can attain even substantial dimensions and weights, and therefore their storage is often problematic.
  • Some known apparatuses insert each bag to be filled in suitable chambers from which air is aspirated; as an alternative, air is also aspirated from the inside of the bag through filtering probes, which are extracted from said bag.
  • air is also aspirated from the inside of the bag through filtering probes, which are extracted from said bag.
  • the apparatuses currently in use tend to leave inside the filled bags holes or labyrinths, which even if they are very small cause the loss of the air and of part of a product and further leave inside the bags an amount of air which is often not tolerable and causes product deterioration.
  • the apparatuses currently in use leave inside such bags an amount of air and/or gas that does not allow to palletize them and causes the deterioration of the product inside.
  • the bags made of polythene (or other similar material), are heat-sealed at the top, after filling and vacuum generation, at a portion of the bag that has been soiled by the product during filling and vacuum production: accordingly, the quality of such heat-seal is certainly not ideal.
  • the aim of the present invention is to obviate the drawbacks noted above, by providing a bagging apparatus that allows to vacuum-package products in bags, even large ones, efficiently and at production rates that are distinctly higher than those that can be achieved currently with known types of apparatus.
  • an object of the present invention is to provide a bagging apparatus that is suitable to package products safely and effectively, without leaving microcracks in the bags or air inside them in an unwanted amount.
  • Another object of the present invention is to provide a vacuum bagging apparatus that is suitable to package the products in bags having standardized and uniform sizes, which as such are easy to store and transport.
  • Another object of the present invention is to provide a bagging apparatus with a structure that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
  • the present bagging apparatus particularly for granular and powdery products, of the type adapted to vacuum-package granular and/or powdery products in bags, characterized in that it comprises at least one bag compaction chamber, in which at least one of the walls is movable and is adapted to apply a given pressure to a surface of the bag, so as to expel therefrom contained air and/or gases and compact the product, and at least one bell, which is provided with at least one filter probe, which is connected to air and/or gas suction means and is adapted to produce vacuum inside the bag, said bell being associated with means for bidirectional translational motion from an inactive retracted position to a suction position, in which it is at least partially inserted in a mouth of the bag so as to adhere perimetrically to its internal surface, means being further provided for heat-sealing the mouth in the portion arranged in contact with said bell, said means being adapted to provide final closure of the mouth of the bag along the internal
  • the reference numeral 1 generally designated a bagging apparatus particularly for granular and/or powdery products according to the invention.
  • the bagging apparatus is in particular of the type suitable to vacuum-package granular and/or powdery products in bags of the type with an open mouth or of the type formed continuously from a reel, generally designated by the reference numeral 2, the mouth of which is designated by the reference numeral 2a.
  • bags are preferably made of a material such as laminated polythene or the like, but actually can be made of any material that has suitable physical and/or mechanical characteristics.
  • the bags can have any geometry or size, which are chosen in each instance in relation to the type of product to be packaged, to the storage conditions, to the methods of transport, and others.
  • the vacuum bagging apparatus 1 described hereinafter has a sturdy footing, provided with dimensions which are suitable for the maximum dimensions of the bags 2 to be filled.
  • the footing of the apparatus is not shown for the sake of simplicity and clarity in the accompanying drawings, but it is of a substantially traditional type.
  • the apparatus comprises advantageously at least one bag compaction chamber, generally designated by the reference numeral 3, in which at least one of the walls is movable and is suitable to apply an appropriate pressure to the outer surface 4 of the bag 2, so as to expel the air contained therein and compact the product in an optimum manner; the apparatus further comprises conveniently at least one bell 5, which is provided with at least one filter probe 6 which is connected to means for aspirating air and/or gases, not shown in the figures, and is suitable to produce vacuum inside the bag 2.
  • the bell 5 is in fact associated conveniently with means for bidirectional translational motion, not shown in the figures but of a substantially known type, from an inactive retracted position ( Figure 1) to a suction position, in which it is at least partially inserted within the mouth 2a of the bag 2 so as to adhere perimetrically to its internal surface 7.
  • the apparatus 1 further advantageously comprises means, generally designated by the reference numeral 8, for heat-sealing the mouth 2a in the portion thereof that is arranged in contact with the bell 5: the heat-sealing means 8 are suitable to produce the final closure of the mouth 2a of the bag 2 along its internal surface 7, which conveniently has remained unsoiled by the powdery and/or granular product, since it has been placed in contact with the external surface 9 of the bell 5.
  • the apparatus in fact comprises, for this purpose, clamping means, generally designated by the reference numeral 10, which are suitable to make the mouth 2a of the bag 2 adhere hermetically to the outer surface 9 of the bell 5, so as to prevent the seepage of air from the outside during the production of the vacuum and/or the escape of the product.
  • the apparatus according to the invention further comprises conveniently elements, generally designated by the reference numeral 11, for temporarily closing the bag 2 substantially at the base of the mouth 2a: the temporary closure elements 11 are suitable to clamp the walls of the bag 2a against each other and thus prevent the inflow of air into the already-filled bag and the escape of the product during the final heat-sealing step.
  • the bell 5 is positioned advantageously at the top of the compaction chamber 3 and is actuated so as to perform a bidirectional translational motion, first downward and then upward, at each packaging cycle, along a substantially vertical direction.
  • the bell 5 can be stationary and the bag can rise vertically, but substantially the operating cycle does not change.
  • the filter probe 6 is in turn fitted inside the bell 5 and is actuated by respective translational motion elements (not shown for the sake of simplicity, but of a substantially known and traditional type) from an inactive retracted upper position to a position which protrudes downward and in which the probe 6, with the bell 5 inserted in the mouth 2a of the bag 2, is substantially in contact with the product contained in the bag, so as to remove the air included in the product in an amount that depends on the type of the product.
  • respective translational motion elements not shown for the sake of simplicity, but of a substantially known and traditional type
  • the compaction chamber 3 comprises at least five substantially flat walls, at least one of which is movable: a first side wall 12 and a second side wall 13, which are mutually parallel and flat, a third bottom wall 14, which is substantially perpendicular to the first and second walls, a fourth upper wall 14a and a fifth upper wall 14b, which are contoured and perpendicular with respect to the side walls 12 and 13 and are flat and parallel with respect to the bottom wall 14.
  • the first wall 12, the second wall 13, the third wall 14, the fourth wall 14a and the fifth wall 14b are associated with respective actuation means, for example of the electrical, pneumatic or hydraulic type, or even of another type, which allow to apply to the bag 2 the suitable pressure, such as to compact the product and at the same time cause the rapid exit of the air included in the product.
  • actuation means for example of the electrical, pneumatic or hydraulic type, or even of another type, which allow to apply to the bag 2 the suitable pressure, such as to compact the product and at the same time cause the rapid exit of the air included in the product.
  • the first wall 12, the second movable wall 13 and the third movable wall 14 are associated with means for generating a vibration of predefined frequency and amplitude, so as to facilitate the compaction of the product inside the bag 2 and cause the air to exit.
  • the vibration generation means may be of a substantially known and traditional type.
  • the heat-sealing means 8 suitable to seal each filled bag 2 comprise advantageously at least one pair of heat-sealing heads 15, which are mutually opposite and are associated with respective actuation elements; each head is actuated so as to perform a translational motion, substantially at right angles to the bell 5, from a respective inactive retracted position to a respective protruding position, in which they are pressed against the external surface of the mouth 2a of the bag 2, for a suitable time interval and at a suitable temperature, so as to produce the hermetic closure of the bag 2.
  • the clamping means 10 conveniently comprise at least one pair of mutually opposite jaws 16, which are associated with respective actuation elements and are each actuated so as to perform a translational motion, in a direction which is substantially perpendicular to the bell 5, from a respective inactive retracted position to a respective protruding position, in which each presses the internal surface 7 of the mouth 2a of the bag 2 against the external surface 9 of the bell 5.
  • the temporary closure elements 11 advantageously comprise a first male element 17 and a second female element 18, which are mutually opposite and are associated with respective actuation elements, not shown in the figures, each of which is actuated so as to perform a translational motion, substantially at right angles to the bell 5, from a respective inactive retracted position to a respective protruding position, in which they are engaged within each other, so as to clamp the base of the mouth 2a of the bag 2, so as to prevent the escape of the product and the inflow of air during the step for final hermetic sealing of the bag.
  • the operation of the vacuum bagging apparatus is as follows.
  • the bag 2 is filled with the granular and/or powdery products to be packaged, subsequently positioning it in the compaction chamber 3 ( Figure 1); filling is performed preferably from above by means of a feeder of the generally known type. Filling can occur advantageously in successive steps, i.e., in several periods separated by air suction steps.
  • the bell 5 is inserted in the mouth 2a of the bag 2, moving it downward by an extent of preset length; the jaws 16 are then clamped, moving the internal surface 7 of the mouth 2a so that it adheres hermetically against the external surface 9 of the bell 5, preventing the seepage of air and the escape of the product ( Figure 2).
  • the fourth wall 14a and the fifth wall 14b and then the first wall 12, the second wall 13 and the third wall 14 are actuated, together with the vibration generation means, so as to achieve the optimum compaction of the product inside the bag and the escape of the air included within said product.
  • the filter probe 6, in this step is in contact with the product: by actuating the air suction means, said air is removed completely from the inside of the bag, providing the required condition of vacuum packaging, which is adjustable according to the requirements of the product ( Figure 4).
  • the first male element 17 and the second female element 18 are actuated so as to perform a translational motion toward each other at right angles to the mouth 2a of the bag 2, so as to close temporarily and hermetically the compacted bag at the base of the mouth 2a ( Figure 6).
  • the jaws 16 are then released from the mouth 2a of the bag, and the bell 5 is extracted completely (Figure 7).
  • the heat-sealing heads 15 are actuated so as to close hermetically and permanently the bag 2 in vacuum, the first male element 17 and the second female element 18 are released, and all the walls 12, 13, 14, 14a, 14b are reopened, so as to be able to remove the bag 2 from the compaction chamber 3.
  • the bag 2 has two flat and parallel regular lateral faces and two top and bottom faces, which are perpendicular to the lateral faces.
  • the bag 2 advantageously has dimensions which are predefined with narrow tolerances (in particular as regards width and height) and is conveniently suitable to be stored and palletized with minimal space occupation and maximum stability and safety.
  • the apparatus according to the invention allows to perform effectively, in particular by virtue of the presence of the bell, the vacuum packaging of the products with minimal air residues and with extremely short operating times. Moreover, the resulting bag has minimized space occupation and regular geometries.
