Definitions

  • the object of the present invention is a bagger.
  • baggers of the type comprising:
  • baggers comprising a wound strip that is unwound and cut into portions that are gripped sequentially and conveyed beneath the filling machine.
  • the strip is constituted by a flattened tubular element so as to have two faces overlap.
  • the stage of conveying the portions beneath the filling machine is carried out by gripper hands that grip one end of the portion, overturn it and at the same time, draw the two overlapped faces away from each other by means of special suction cups so as to make an "opening" in the tubular portion.
  • the technical task underlying the present invention is to improve the productivity of the bagger while simultaneously optimizing the components with the aim of minimizing the costs thereof.
  • a bagger 1 is indicated by the reference number 1.
  • the bagger comprises forming means 200 for forming a bag that is apt for receiving a product to be bagged.
  • This product may be of any sort, preferably a granular or powdery material.
  • the forming means 200 comprises a forming body 2 that is apt for passing inside a first tubular tract 3 that is intended to create said bag.
  • This forming body 2 can also be called the forming tube.
  • the forming body 2 is also a retractor for retracting two overlapped edges of said first tubular tract 3.
  • the forming body 2 advantageously has a divergent element 23 that is cone-shaped or truncated cone-shaped for example.
  • the bagger 1 comprises feed means 8 for feeding a continuous strip to the forming body 2, said continuous strip being defined by tubing with two faces that are overlapped and/or adhering one to the other.
  • the feed means 8 suitably comprises a reel 80 for storing said strip.
  • the forming means 200 suitably comprises closing means 6 for closing at least one edge of said first tubular tract 3.
  • the bagger 1 advantageously comprises gripping means 4 for gripping the forming body 2 and also comprising at least a first and a second supporting means 41, 42 for supporting the forming body 21.
  • the first supporting means 41 grips the forming body 2 upstream of the second supporting means 42 with respect to the feed direction of the first tubular tract 3.
  • the first supporting means 41 conveniently comprises a projection (e.g. a pin or a peg) that is insertable in a corresponding hole found on the forming body 2. The same can be repeated for the second supporting means 42.
  • the forming body 2 thus hangs from the first and/or second supporting means 41, 42.
  • the first supporting means 41 (and advantageously the second supporting means 42) performs its gripping action on the forming body 2.
  • the first supporting means 41 does not carry out a gripping action on the forming body 2 so as to permit passage of the first tubular tract 3 (while the second supporting means 42 performs its gripping action on the forming body 2, thereby preventing it from dropping).
  • the second supporting means 42 performs its gripping action on the forming body 2, unlike the first supporting means 41.
  • the first and second supporting means 41, 42 are hydraulically activated. This improves operating reliability.
  • the forming body 2 has a prevalent axial direction 21 of extension.
  • the forming body 2 conveniently extends prevalently between the top and the bottom.
  • the forming body 2 preferably extends vertically.
  • An inlet zone of the forming body 2 e.g. the divergent element 23
  • an exit zone for exiting from the forming body 2 is found at the bottom.
  • the forming body 2 conveniently comprises partitions that are movable transversely with respect to the prevalent axial direction 21 of extension (advantageously, these partitions move radially with respect to the axial direction 21 of extension). In this manner, the widening of said first tubular tract 3 can be adjusted.
  • at least one of said partitions is connected to a worm screw driven by an electric motor.
  • the bagger 1 conveniently comprises cutting means 5 that separates said first tubular tract 3 from continuous tubing.
  • the continuous tubing consists of the strip coming from the feed means 8.
  • the cutting means 5 thus makes it possible to adjust the length of the eventual bag.
  • the cutting means 5 defines a path encircling said forming body 2 so as to cut the first tubular tract 3.
  • the cutting means 5 could conveniently comprise a mechanical blade (preferred solution), but it could also comprise a nozzle that generates a jet of pressurized liquid or a laser ray or something else.
  • the cutting means 5 preferably comprises a thrust bearing.
  • the cutting means 5 comprises a drive gear for moving a cutting element (blade, nozzle or something else).
  • a cutting element blade, nozzle or something else.
  • at least said gear is made of Teflon. This makes it possible to minimize the weight of the cutting means 5.
  • the bagger 1 conveniently comprises a first clamp 43. Conveniently, this first clamp 43 cooperates with driving means 44 for driving the first tubular tract 3 so as to define tensioning means for tensioning the first tubular tract 3.
  • the driving means 44 comprises a belt intended to come into contact with a surface of the first tubular tract 3 and that frictionally drags the first tubular tract 3.
  • the cutting means 5 is interposed between the first clamp 43 and the driving means 44 of the first tubular tract 3. Thus the cutting means 5 is able to cut the first tubular tract 3, thereby separating it from the remaining tubing. In a similar manner, the cutting means 5 is located upstream of the first supporting means 41 with respect to the feed direction of the first tubular tract 3 along said forming body 2.
  • the bagger 1 can conveniently comprise auxiliary driving means 45 interposed between the first clamp 43 and the cutting means 5.
  • This auxiliary driving means 45 facilitates advancement of the first tubular tract 3.
  • the bagger 1 comprises a second clamp 46.
  • This second clamp 46 is located downstream of the second supporting means 42.
  • the task of the second clamp 46 is to keep the bag integral with the forming body 2.
  • the forming body 2 conveniently comprises an inlet 20 at a lower end for insertion of the product in the bag.
  • the bagger 1 further comprises a filling tube 9 that is operationally interposed between a storage tank 90 for storing the product and the inside of said forming body 2 (and thus the insertion inlet 20).
  • the storage tank 90 can comprise a storage hopper 91 that leads into a metering hopper 92, which makes it possible to meter the amount of product that flows into each bag.
  • the filling tube 9 is moved away from the forming body 2.
  • the first tubular tract 3 can thus pass in a space interposed between the forming body 2 and the filling tube 9.
  • the filling tube 9 leads into said forming body 2 (to transfer the product from the storage tank 90 to the forming body 2).
  • the filling tube 9 advantageously comprises at least one sliding tract that moves away or close to the forming body 2.
  • the forming body 2 comprises a lateral opening 93, in which, in the second operational mode, the filling tube 9 is partially inserted.
  • the second clamp 46 is found downstream of said lateral opening 93.
  • the second supporting means 42 is found downstream of said lateral opening 93.
  • the closing means 6 is conveniently located downstream of said inlet 20.
  • the closing means 6 comprises sealing means.
  • This sealing means 6 seals two lower edges of said first tubular tract 3 to obtain a bag that is open at the top (and advantageously also seals the two upper edges of the first tubular tract 3 so as to close the bag filled with the product).
  • the bagger 1 comprises a carousel located downstream of the forming body 2.
  • This carousel can include closing means 6.
  • the carousel can comprise a plurality of stations where a predetermined activity is performed in each one.
  • the object of the present invention is also a method for packaging a product in a bag.
  • This method is conveniently implemented by a bagger 1 comprising one or more of the characteristics disclosed hereinabove. This method comprises the stages of:
  • the method comprises the stage of cutting the first tubular tract 3, separating it from continuous tubing located upstream.
  • the continuous tubing is tubing coming from the reel 80.
  • the stage of cutting the first tubular tract 3 takes place when the first tubular tract 3 is fitted on and encircles the forming body 2.
  • the stage of cutting the first tubular tract 3 provides for moving the cutting means 5 around the forming body 2.
  • the stage of cutting the first tubular tract 3 is contemporaneous with the stages of:
  • the method further comprises the stage of sealing two edges of a first end of the first tubular tract 3, thereby obtaining a bag that is open at a second end of the first tubular tract 3.
  • the stage of sealing the first end of the first tubular tract takes place after the first end has arrived downstream of the forming body 2 (in fact, in this zone the opposite edges can come close to each other again as the forming body 2 is no longer interposed therebetween).
  • the first end of the first tubular tract 3 is the lower end of the first tubular tract 3.
  • the method then comprises insertion of the product in said open bag, passing it through an inlet 20 of the forming body 2 leading into said open bag.
  • the stage of inserting the product in said bag comprises passing the product through said inlet 20, which lies at an exit end of the forming body 2.
  • the exit end of the forming body 2 is found at a lower end of the forming body 2.
  • the insertion inlet 20 thus faces downwards and passage of the product takes place by gravity.
  • the forming body 2 extends prevalently between the top and the bottom; during the stage of inserting the product in said open bag, the upper edges of the bag encircle and are in contact with the forming body 2 so as to minimize depositing of the product on the upper edges of the bag (which could negatively affect the subsequent sealing of the second end).
  • the stage of inserting the product in said open bag by passing it through an inlet 20 of the forming body 2 is preceded by the stage of moving a filling tube 9 to insert one end of the filling tube 9 in said forming body 2 through an opening 93 (setting a tank of the product in communication with said inlet 20 of the forming body 2).
  • the stage of feeding at least a first tubular tract 3 around the forming body 2 comprises having said first tubular tract 3 move beyond the opening 93 so that the opening 93 sets the inside and the outside of the forming body 2 in communication (without the opening being obstructed by the first tract 3).
  • the method comprises the stages of:
