Definitions

  • the present invention relates to a convertible container for the transportation of mixed goods, which can transport efficiently both so-called “bulk” goods, such as grains, cereals, polymer granules, etc., and any other type of goods.
  • “bulk” goods such as grains, cereals, polymer granules, etc.
  • the most common logistic process includes:
  • This transport system involves complex logistics for the various steps and operations involved, a high operating cost due to the considerable handling of the goods in the transfer to and from the various silos, the cargo beds of the road or rail vehicles, the ship holds, etc., a handling that in some cases can also affect the quality of the goods, and a high management cost.
  • the object of the present invention is to overcome the drawbacks of the state of the art by providing a convertible container suitable for transporting in bulk cereal food products or flours, but which is at the same time fully comparable to, and usable as, a standard container, suitable for transporting non-bulk goods, such as boxes, machinery, etc.
  • reference numeral 1 indicates a container for the transportation of in bulk and non-bulk goods, comprising a self-supporting substantially rigid casing 2 delimited by a floor 3, a ceiling 4 and respective lateral walls 5, 6, 7, and by a rotating door 8 arranged at a first longitudinal end 9 of the casing 2.
  • the rotating door 8 is of a known type, generally with two leaves, of which only one is illustrated for simplicity in Figures 1 and 2 .
  • the container 1 further comprises at least one foldable and flexible bag 10 mounted inside of the casing 2.
  • the bag 10 has a volume such as to occupy, in an expanded configuration ( Figure 2 ), a space in height substantially equal to a distance in height between the floor 3 and the ceiling 4 of the casing 2.
  • the casing 2 and the bag 10 have a substantially parallelepiped shape
  • the bag 10 is fixed hung from the ceiling 4 by an upper portion 11 thereof in any suitable way and not shown for simplicity and the bag 10 has, in the expanded configuration, an external volume substantially equal to or slightly less than the internal volume of the casing 2, for example it has a longitudinal extension just below that of the casing 2, so as to leave free a part of the interior of the end 9 of the casing 2, proximal to the door 8.
  • the shape of the bag 10 is also such that, when it is in an expanded configuration (for example it is full) it almost completely assumes, as will be seen, the shape of the casing 2.
  • the casing 2 is made of a corrugated metal welded and/or bolted sheet, in a known manner.
  • the container 1 also comprises at least one loading/supplying pipe 12 for loading bulk goods 13 ( Figures 4 , 5 ) inside the bag 10 itself.
  • the loading pipe 12 is arranged immediately adjacent to the ceiling 4, between the latter and the bag 10, for example fixed integral with the ceiling 4 in any convenient manner and is connected hydraulically with the interior of the bag 10.
  • the container 1 further comprises at least one unloading pipe 14 for unloading bulk goods 13 from inside of the bag 10.
  • the unloading pipe 14 is connected integral with the bag 10 at a bottom portion 15 of the bag 10 facing the floor 3 of the casing 2 and is also hydraulically connected with the inside of the bag 10, which, apart from the connections with the pipes 12 and 14, is generally a closed element, or open only at the top, i.e. towards the ceiling 4, at the upper portion 11, which in this case delimits only the perimeter thereof.
  • the bag 10 is made with known materials and technologies but suitably adapted for the specific use.
  • a fabric suitable for food transport is selected in compliance with international regulations.
  • the fabric is of the TREVIRA® type, for example it is made of a polyethylene glycol terephthalate or equivalent, which is very resistant to loads and which allows the appropriate transpiration necessary for the in bulk goods 13 transported when this consists of cereals, as in the preferred embodiment.
  • the container 1 further comprises a plurality of first tie rods 16 connected integral with a lateral wall 18 of the bag 10, at an upper portion 11 of the bag 10 itself, opposite to the bottom portion 15.
  • the container 1 further comprises a traction device 19 connected to the first tie rods 16 and configured to normally hold the bag 10, when the bag 10 is empty, in a first configuration, partially packaged, schematically illustrated in Figure 3 .
  • the bag 10 is partially folded in on itself.
  • the partial folding of the bag 10 is schematised purely by way of non-limiting example and without the pretense of likeliness in Figure 3 , where the lateral wall 18 of the bag 10, shown only in its part adjacent to the wall 5, forms folds 20, schematically illustrated only in Figure 3 for simplicity.
  • the unloading pipe 14, integral with it is arranged against the floor 3 of the casing 2.
  • the bag 10 itself forms with the bottom portion 15 thereof a funnel 21 ( Figure 3 ) delimited towards the lateral walls 5, 6 by a slanted surface or plane 22 ( Figure 3 ).
  • the traction device 19 and the bag 10 are configured so that the slanted surface 22 of the funnel 21, in the first configuration illustrated in Figure 3 , has an angle greater than the sliding angle of the in bulk goods 13 to be transported, an angle which depends on the chemical-physical nature of the goods 13 and therefore varies with the type of goods 13 to be transported, but which is known in the literature, for each type of goods 13.
  • the container 1 further comprises second tie rods 23 integral with a bottom wall 24 of the bag 10, delimiting the bottom portion 15 of the bag 10 towards the floor 3 of the casing 2.
  • the tie rods 23 can be arranged outside the bag 10, at the end 9 of the casing 2 and at an opposite longitudinal end 25 thereof ( Figures 1 and 2 ), as shown in a non-limiting manner and only schematically, or also be, in the event of the presence of more than two tie rods 23 for each end 9,25, because for example the tie rods 23 are distributed along the length of the casing 2, partially housed within the bag 10, for example passing through it, for example fluid-tight or at least dust-tight.
  • the second tie rods 23 are also connected to the traction device 19, which is configured to apply tension to the second tie rods 23 before to the first tie rods 16 and as a consequence of a process of emptying the bag 10 of the in bulk goods 13, as will be seen, so as to raise at least part of the bottom wall 24 of the bag 10 with respect to the floor 3 of the casing 2.
  • the second tie rods 23 are fixed to the bottom wall 24 of the bag 10 in an intermediate position comprised between the first tie rods 16 and the unloading pipe 14.
  • the first tie rods 16 are/can be in a large number, greater than that formed by a pair of tie rods 16 arranged at each end 9, 25. In this case, they are arranged at the respective opposite lateral walls 5, 6 of the casing 2 which delimit the sides thereof, longitudinally in sequence and spaced apart from each other along the entire longitudinal extension of the bag 10, parallel to the opposite lateral walls 5, 6, as schematically illustrated in Figure 1 .
  • the traction device 19 comprises means for countering the weight of the bag 10 and of the bulk goods 13, connected to the first and second tie rods 16, 23 and configured to hold the bag 10 in said first configuration when the bag 10 is empty and in the expanded configuration ( Figure 2 ) when the bag 10 is full.
  • such means for countering the weight of the bag 10 and of the bulk goods 13 consist of first counterweights 26 constrained to the first tie rods 16 and of second counterweights 27 constrained to the second tie rods 23.
  • the counterweights 26, 27 are housed slidingly within respective guides 28, illustrated only schematically and only in Figure 3 , integral with the opposite lateral walls 5, 6 of the casing 2.
  • the guides 28 are arranged inside respective interspaces 29 ( Figure 3 ) delimited by the lateral walls 5, 6 of the casing 2, or on an inner face 30 ( Figure 4 ) of the same facing towards the loading pipes 12 and the unloading pipes 14, according to configurations that are apparent to the person skilled in the art and therefore not illustrated in detail for simplicity.
  • the means for countering the weight of the bag 10 and of the bulk goods 13 are constrained integral with the first and the second tie rods 16, 23 and are selected from the group consisting of: counterweights, such as the counterweights 26, 27 of the preferred embodiment; preloaded hydraulic or pneumatic mechanical springs, pneumatic or electrical hydraulic actuators housed inside the casing 2; a mechanical transmission gear 31 ( figure 2 ) illustrated only schematically with a block, connected with the first and second tie rods 16, 23 and connectable via a power take-off 32 to a motor 33 outside of the casing 2.
  • the traction device 19 also includes everything needed to operate the tie rods 16 and 23 and manipulate and shape the bag 10, such as pulleys 34 ( Figures 1 and 2 ), return pulleys, etc., whose structure and arrangement are apparent to those skilled in the art and therefore are not illustrated in detail for simplicity.
  • At least the first tie rods 16 are arranged at the respective opposite lateral walls 5, 6 of the casing, as schematically illustrated in Figures 1 to 7 , and the traction device 19 is configured to allow the bag 10, when full, to assume the expanded configuration ( Figure 2 ), in which the bottom wall 24 of the bag 10 rests against the floor 3 of the casing 2, together with the pipe 14, integral with the bottom portion 15 of the bag 10, precisely at the bottom wall 24.
  • the loading pipe 12 and the unloading pipe 14 are arranged facing the rotating door 8 and are provided, towards the rotating door 8, with respective connection inlets 35 to loading 36 and reception 37 means outside of the casing 2 ( Figure 1 ), illustrated only schematically.
  • the container 1 comprises means 38 ( Figure 8 ) for winding the bag 10, when it is in the first configuration, partially packaged in Figure 3 , in a second configuration, completely packaged, illustrated in Figure 8 , in which the bag 10 is completely folded in on itself and is arranged together with the unloading pipe 14 integral thereto against the ceiling 4 of the casing 2.
  • the means 38 can be of any type, for example they can consist of tie rods (not shown) connected to the pipe 14, which allow the bag 10 to be lifted, making it pass from the configuration of Figure 3 to that of Figure 8 and block it in the latter configuration.
  • the bag 10 when empty, assumes the shape shown in Figure 3 , with the bottom wall 24 slanted with an angle greater than the sliding angle of the bulk goods 13 and held in position by external mechanisms consisting of the tie rods 16, 23, the traction device 19 and, in the example given by way of example only, of the counterweights 26, 27 arranged in their lowest position.
  • the bottom portion 15 of the bag 10 deforms, the bag 10 stretches and fills the lower space of the casing 2 and the counterweights 26 and 27 begin to move upwards ( Figure 5 ), until they move to a position of maximum elevation.
  • the counterweights 27 are activated raising part of the bottom wall 24, shaping the bottom portion 15 of the bag 10 ( Figure 6 ) according to the imbalance of the forces involved (weight of the goods 13 residual in the bag 10 and weight of the counterweights 27 and 26).
  • the counterweights 27 first and then also the counterweights 26 begin to descend and lift the bottom wall 24 of the bag 10, thus making the granular material or goods 13 pass the sliding angle and allowing the unloading to continue ( Figure 7 ) until the bag 10 is completely empty.
  • the bag 10 and the loading pipe 12 and unloading pipe 14 are wound on the ceiling 4, thanks to the fact that the pipes 12 and 14 are housed laterally offset from each other, so that when the bag 10 is packaged they lie side by side.
  • the bag 10 and the pipes 12, 14 can be wound against one of the lateral walls 5, 6, by sliding, for example on suitable transverse guides, not illustrated for simplicity.
  • the container 1 can be used for the transport of other types of goods 39 ( Figure 8 ), thus extending its use to the whole year and also during the return trips. All the objects of the invention are achieved.
