Definitions

  • the present invention fits in the area of the devices for shaking and emptying bags. It's a device that enables bags to be shaken dynamically by means of circular and linear movements in different planes and directions and, thus, emptying them.
  • the present invention finds its closer backgrounds in equipment for the automatic emptying of bags which are not dynamic, that is, that only provide linear or circular movement while shaking the bags, thus, never doing it in a simultaneous and integrated way.
  • Such devices known in the present state of the art, are not sufficiently configurable for each particular application, i.e. they do enable the increase or decrease of the frequency of the linear or circular motion transferred to the bags but they do not allow increasing the intensity or the amplitude of such movement.
  • Patent application EP 3070014 A1 and patent EP 1838582 B1 are examples of the present state of the art devices that are closest to the present invention.
  • the present invention has been envisaged to provide an automatic bags emptying equipment that would improve the efficiency of this process. Ideally, it would be able to empty 100% of the content of the bags in a very short time. In other words, it's intended to empty the bags as much as possible in the shortest time, improving the results obtained when compared to the manual accomplishment of this task and, also, when compared to the use of the presently known automatic bag emptying devices.
  • the subject of the present invention is a dynamic shaking device for emptying bags that enables the simultaneous linear and circular movement and also in different planes of the bags to be emptied, since it has shakers composed of serpentine-shaped agitating elements (5) that causes the bags to be shaken in all directions at the same time (up, down, left, right, front, back) resulting in a dynamic shaking.
  • This dynamic system introduces movement in several directions at the same time, due to the circular movement of the shakers which is transformed into ascending / descending actions and left / right displacement applied on the opened bags.
  • the present invention comprises three central elements:
  • the invention presents the bags opening zone, in which bags are opened by cutting their bottom.
  • This action is carried out by at least one rotary shaft (1) disposed perpendicularly in relation to the direction of the movement of the bags.
  • Each rotary shaft (1) supports at least one cutting disc (2) with blade at the outer edge, responsible for opening the bags during its horizontal displacement.
  • the number of rotary shafts (1) and cutting discs (2) is configurable.
  • the present invention enables the simultaneous linear and circular motion in different planes of the bags to be emptied, this being the main innovation of this device.
  • the bags cutting zone follows the bags shaking zone, in which one can find at least one shaker driven by proper means (for example an electric motor) that comprises a serpentine-shaped shaker element (5) where the serpentine development is perpendicular to the direction of the movement of the bags, e.g. parallel to the rotating shafts (1) of the cutting zone.
  • the invention may have a central shaft (4) inside the serpentine-shaped shaker element (5) and these two parts may be interconnected by means of plates, bars or rods.
  • the serpentine-shaped shakers (5) can be built from a round rod, a squared rod, a strip of sheet metal, or from any other material as long as they develop in the form of a serpentine.
  • the serpentine-shaped shaker elements (5) have various diameters in their serpentine development, and/or different diameters between shakers (5) providing that the device has, at least two of these.
  • the device can also present, alternatively, serpentine-shaped elements developed in clockwise and counter-clockwise direction, being those called as shaker elements (5) and counter-shaker elements (5a).
  • the period of the geometrical development of the serpentine is done alternately and the maximum amplitude of the serpentine curve of one shaker element (5) occurring symmetrically to the maximum of the amplitude of the serpentine curve of the counter-shaker (5a).
  • the design and application of the serpentine-shaped shaker elements (5) and, in a specific arrangement, of the counter-shaker elements (5a) enables the movement of the bags in all directions at the same time (up, down, left, right, front, rear) resulting in a dynamic shaking.
  • the present invention provides the possibility of controlling the frequency/speed of the shaker elements (5) and counter-shaker elements (5a), as well as the intensity of their rotation by means of controlling the shakers drive, thus adjusting the intensity of the movement to the type of bag and product to be emptied.
  • the present invention has two rotary shafts (1), each with fourteen cutting discs (2), followed by eight shakers driven by an electric motor (3). These rotary shafts (1) and the central shafts (4) are secured in a metal frame at their ends.
