Definitions

  • the present invention relates to a packaging machine with increased functionality, particularly for small preformed bags, and a packaging method, particularly for packaging small preformed bags, which can be carried out with the packaging machine.
  • Conventional packaging machines are generally provided with discharge outlets that are designed as a function of the size or of the shape of the bags to be filled and which must be totally or at least partially substituted with every change of format.
  • packaging lines present on the market are not capable of packaging all the kinds of bags (of different types, sizes and materials) that are present on the market with a single model of machine.
  • BE 515 333 A , FR 2 780 027 A1 , DE 2629065 A1 and EP 2078674 A1 disclose packaging machines having a plurality of processing stations which are arranged along at least one advancement line and which are provided with retention means and opening means for at least one bag to be filled which are connected functionally to means for the advancement of the bag to be filled along the advancement line, said processing stations comprising at least one filling station that is provided with at least one filling cone that is adapted to discharge loose products into the bag to be filled, which is opened and shaped beforehand.
  • the filling cone can move between a minimum opening, in which the filling cone assumes a substantially pyramid-like shape with an acute angle, and a maximum opening, means being also provided for lifting and lowering either or both of the bag to be filled and the filling cone for a partial insertion of the filling cone into the bag to be filled.
  • EP 2078674 A1 discloses that the filling cone in the maximum opening assumes a substantially parallelepiped shape and is defined by two half-shells, which are pivoted at an outlet of a duct for feeding the loose products and are substantially shaped like an open vat, which is delimited by a central wall substantially parallel to a discharge direction of said loose products and by two side walls.
  • EP 2078674 A1 also discloses two mutually opposite suckers that can move toward and away from each other at right angles to the advancement line so as to open the bag before it is moved to the filling cone.
  • EP 2078674 A1 also discloses the use of grippers according to JP2002-302227A , which retain the bag at the lateral portions and are movable toward and away from each other parallel to the advancement line.
  • EP 0082955 A2 discloses a bag filling apparatus with means for gripping bags adjacent to their top and side edges, vacuum cups for pulling the top edges apart and a filling cone with half shells, which bear vacuum pipes on their rear walls and are hinged on respective axes transverse to the line connecting the grippers.
  • the arrangement is such that, in the filling position and with the bag gripped by the grippers, the top edge of the bag is tensioned so that no dust can escape on the sides.
  • the aim of the present invention consists in providing a packaging machine with increased functionality which is capable of overcoming the above-mentioned drawbacks and limitations.
  • an object of the present invention consists in providing a packaging machine that is particularly adapted to the packaging of small preformed bags.
  • Another object of the present invention consists in providing a packaging machine that is capable of offering the widest guarantees of reliability and safety of use.
  • the packaging machine with increased functionality particularly for small preformed bags, generally designated with the reference numeral 1, comprises a plurality of processing stations which are arranged along at least one advancement line 2 and which are provided with retention means 3 and opening means 4 for at least one bag 5 to be filled which are connected functionally to means for the advancement of the bag 5, which are not shown since they are conventional.
  • the bag 5 can be a preformed bag of the type with an open mouth with or without lateral accordion portions, an open mouth with or without a bottom, an open mouth with or without a handle, or an open mouth of the Doy Pack type, or stand-up pouch, or Top Slider, etc.
  • These preformed bags can furthermore be made from materials of different types, and the sizes of the bags that can be processed can vary from 300 grams up to 7 kilograms.
  • the processing stations comprise at least one filling station that is provided with at least one filling cone 6 that is adapted to discharge loose products 7 into the bag 5, which is opened and shaped beforehand.
  • each filling cone 6 is of the type with variable opening so that it can move between an active configuration of minimum opening, in which it assumes a substantially pyramid-like shape with an acute angle as shown in Figures 3 and 4 , and an active configuration of maximum opening, in which it assumes a shape substantially like a parallelepiped with a rectangular cross-section as shown in Figures 5 and 7 .
  • means are provided, also not shown, for lifting and lowering either or both of the bag 5 and the filling cone 6 in order to partially insert the filling cone 6 into the bag 5 along a line of ascent/descent 18.
  • each filling cone 6 is defined by at least two half-shells 8 and 9, which are pivoted at the outlet 10 of a duct 11 for feeding the loose products 7 so that they can move between the active configuration of minimum opening, in which these half-shells 8 and 9 are closed against each other so as to give the filling cone 6 the substantially pyramid-like shape with an acute angle, and the active configuration of maximum opening, in which the two half-shells 8 and 9 are open with respect to each other so as to give the filling cone 6 substantially the shape of a parallelepiped with a rectangular cross-section.
  • the two half-shells 8 and 9 are both substantially shaped like an open vat, which is delimited by a central wall 12, which extends substantially parallel to the discharge direction of the loose products 7, and by two side walls 13, with the central walls 12 being mutually opposite and the central walls mutually offset so as to define a male-female coupling and allow the insertion of the two half-shells 8 and 9 one inside the other and delimit laterally each filling cone 6 in all of its active configurations.
  • the above-mentioned walls 12 and 13 are furthermore shaped so as to define, at the outlet of each filling cone 6, two beaks 14 and 15 which define the vertex of the filling cone 6 and are adapted to be inserted into the bag 5 during the step for filling it.
  • means 16 are provided for adjusting the opening angle of the two half-shells 8 and 9, which comprise, for each half-shell 8 and 9, a pneumatic actuator 17 that is interposed between an abutment 19 that is integral with the feeding duct 11 and an element 20 for supporting the respective half-shell 8 or 9.
  • the filling mouth that is defined enables the packaging, with high productivity, of any bag, irrespectively of the shape, type and size.
  • the above-mentioned opening means 4 comprise at least two mutually opposite sets of suckers 21 that can move toward and away from each other at right angles to the advancement line 2, so as to grip the bag 5 by adhering to the lateral surfaces 23 thereof, following their mutual approach, and so as to open the selvage 24 thereof, following their mutual spacing.
  • the retention means 3 comprise at least two sets of grippers 25 which are mutually opposite and movable toward and away from each other at right angles with respect to the advancement line 2 so as to retain the bag 5 to be filled at its lateral accordion portions 26.
  • the two sets of grippers 25 are movable toward and away from each other parallel to the advancement line 2 so as to allow the complete opening of the bag 5 with the lateral accordion portions 26 retained by the sets of grippers 25 following the thrust applied on the selvage 24 by the beaks 14 and 15 that are inserted into the bag 5, so as to make the selvage 23 adhere to the entire external perimeter of the filling cone 6.
  • At least one sealing station is provided which is arranged behind the filling station or stations and is provided with at least one set of heat-sealing bars 27, which are provided with liquid cooling means of the heat-sealing, for the heat-sealing of the selvage 24 of the bag 5.
  • means are provided for the height adjustment of the heat-sealing bars 27 so as to be able to provide a plurality, for example up to four, of types of closure for different types of bags and/or to be able to provide a plurality, for example three, of different types of closure on the same bag.
  • air removal means 28 are provided for removing the residual air contained in the bag 5, in the transfer thereof from the filling station to the sealing station, which comprise, at their upper part, a series of pressers 29 that are adapted to retain the bag 5 and to make the selvage 24 descend and, at their lower part, a pair of rollers 30 that are adapted to operate vertically on the lateral surfaces 23 of the bag 5, until they reach the level of the product contained therein, so as to eliminate the air between the product and the selvage 24.
  • the packaging method obtainable with the packaging machine 1 described above, particularly for packaging small preformed bags, is described below.
  • the packaging method comprises the following steps:
  • the retention means 3 and the opening means 4 comprise respectively the sets of grippers 25 for retaining the lateral accordion portions of the bag 5 to be filled and the sets of suckers 21 for opening the bag 5; the former operate on the sides of the selvage 24 of the bag 5 to keep the accordion portions closed, and move toward each other on the horizontal axis while, simultaneously, the latter once adhered to the bag 5 move away from each other so that it can be opened in order to make the selvage 5 define an oval-shaped opening.
  • each filling cone 6 and the selvage 6 of the bag 5 to be filled can be mutually coupled and uncoupled thanks to the vertical and horizontal movements of the mouth or of the retention means 3 of the bag 5 which are connected to the supporting frame of the outlet 10.
  • the filling cone 5 can thus partially penetrate the bag 5 and then open horizontally toward the accordion portions and discharge the product 7 into the bag 5.
  • the outlet of the filling cone 6 deforms the initially oval cross-section of the selvage 24 causing it to take on the shape of the outlet itself, i.e. a shape very similar to that of the transverse cross-section of the bag 5 that is now filled, almost rectangular.
  • the outlet of the filling cone 5 moves a part of the accordion portions that are not held in place by the retention means 3 so that the outlet of the filling cone 6 can define a bigger opening, thus exploiting approximately 80% of the width of the selvage 24 of the bag 5.
  • the retention means 3 that hold the selvage 24 of the bag 5 with the accordion portions held in place move apart in order to put the selvage 24 of the bag under tension and make it adhere to the entire external perimeter of the outlet of the filling cone 6.
  • the opening of the outlet of the filling cone 6, in addition to allowing the product 7 to enter the bag 5, also modifies the original, oval-shaped opening of the selvage 24 by making it take on an almost rectangular shape.
  • the filling cone 6 and the selvage 24 are separated and the bag 5 is then gripped by the retention means 3, so that they can hold, align and transport the bag 5, which retention means have a pair of claws or jaws that rotate on a vertical falling plane, in moving apart and coming together.
  • such means of retention, alignment and transport enable the alignment of the selvage 24, by way of a mutual spacing movement along the horizontal axis, and the alignment can be achieved both under the outlet of the filling cone 6, and in a subsequent station.
  • the bag is translationally moved to the subsequent station, for the operations of discharging the air contained in the bag 5 to be filled by way of the air removal means 28 and to heat-seal the selvage 24 by way of the set of heat-sealing bars 27.
  • Such translational motion occurs by way of the grippers for retaining, alignment and transport, accompanied by auxiliary movement means which operate on the bottom of the bag, such as for example conveyor belts and moving arms.
  • the bag is moved to the heat-sealing station directly by the air removal means 28.
  • Such heat-sealing stations can be one or more in number, and on each assembly it is possible to have sets of bars that are adjustable in height, so as to be able to execute up to four different types of closure for different types of bags, or to be able to execute up to three different types of closure for the same bag.
  • the packaging machine with increased functionality, particularly for small preformed bags, and the packaging method obtainable with it, achieve the intended aim and objects since they allow the packaging of different kinds of bags, without the necessity of changing the discharge outlets, so that the machine is adapted for the packaging of both food and chemical products, as well as pet food.
  • bags with different types such as: bags with accordion portions, or without accordion portions, bags with outer handles, bags with punched handles, Doy Pack bags, Stand-Up Pouch bags, Single Life Top Zip bags, Mini Pet Pack bags, Internal Front Zipper bags, Top Slider bags, Hidden Front Slider bags, Easy Open bags.
  • Another advantage of the packaging machine consists in the fact that the handling of the bags on the advancement line always occurs with the accordion portions held in place, so as to ensure the 100% perfect closure of the package.
  • Another advantage of the packaging machine, according to the present invention consists in the fact that it allows an optimal sealing of the bags which is such as to preserve the fragrance and quality of the product.
  • the liquid cooling means of the heat-sealing it is possible to prevent the material of the bag from deforming with the heat, thus taking on an unpleasant appearance; furthermore the system prevents variation in the colors of the bag in contact with the heat sources.
  • Another advantage of the packaging machine, according to the present invention consists in the fact that it is easy to use and quick to effect the change of format, being furthermore reliable from the point of view both of the process and of the work elements over time.
