Definitions

  • the present invention relates to the technical field concerning the management of palletised goods for internal or external logistics and/or storage and transport purposes and refers to a device for separating and managing a part of the load of a pallet assigned, for example, to separate parcels or packages placed in an upper portion of the load of a pallet and to deposit them on a second pallet forming the load thereof, in one or more sequential phases.
  • An object of the present invention is to propose a relatively simple and economical device capable of taking a higher portion of the load from a bench for instanced to reduce the height of the load remaining on such pallet. Another object is to separate the entire load of a pallet from the pallet itself. A further object is to deposit a portion taken from a pallet on another pallet or to stack the portions taken from many pallets forming a total load deposited on another pallet. Another object is to pick up portions of a load made up of one or more layers of parcels or packages. A further object is to pick up, move and deposit portions of the load even if they are delicate, fragile or if they cannot be overturned.
  • Another object is to minimize the risks of fall and/or damage to both the removed part of the load and the part left on the original pallet.
  • FIG. 1 illustrates an axonometric and front view (i.e. from the input and output side for the pallets and for the loads supported by them) of the device for separating and managing part of the load of a pallet, which is the subject of the present invention, in its operating condition in which it base lies on a horizontal plane or floor;
  • figure 2 illustrates a side view of the device of figure 1;
  • figure 3 illustrates an axonometric view of the device of figure 1 in a rest condition prior to a operating cycle
  • FIG. 1-8 illustrate the device of figure 1 associated with a first pallet bearing a load and a second pallet, in a possible sequence of steps for reducing the height of the load of the first bench or pallet and depositing the taken portion of the load onto the second pallet;
  • FIG. 12-17 illustrate axonometric views of an operative sequence carried out by a variant of the device of figure 1.
  • numeral 1 indicates the device for separating and managing a part of the load of a first pallet P, object of the present invention, comprising a gripping member 3 provided with two almost flat walls 5 mutually parallel where such gripping member 3 is connected to a translating member 9 which moves it and is adjacent to a lifting member 17.
  • the term “almost” must be understood in the sense of “within an acceptable approximation within the scope of this application” or, by way of example, the surfaces of the walls can deviate from the geometric plane by a few millimetres or centimetres and, similarly, their mutual distance can vary by a few millimetres or by a few centimetres.
  • the two walls 5 are vertical.
  • At least one of such walls 5 is operated for mutual approaching and distancing of the two walls; preferably both walls are moved perpendicular to themselves and in opposite directions so as to move them apart and closer together to tighten an interposed portion of the pallet load between them and to release such part of the load or to contain the portion of the load between them, without tightening it but to allows the pushing and moving of said portion while maintaining the stability of the latter.
  • the translating member 9 is of the two-axes type, one for the translation of the gripping member 3 in a vertical direction z and the other for the translation of the gripping member 3 in a horizontal direction x where such directions z, x are respectively parallel and perpendicular to the two walls 5.
  • the translating member 9 is capable of raising, lowering and laterally moving the gripping member 3; in such way the gripping and translating members can cooperate to grasp an upper portion of the load, to lift it slightly and to move it laterally towards the lifting member 17, to release such portion of the load and to return to the initial condition.
  • the translating member 9 is able to translate the gripping member 3 in the vertical direction z up to a predetermined maximum height, equal to or higher than that of the load C of the first pallet P, and in the horizontal direction between a first extreme position in in which the gripping member 3 is superimposed on a first site 11 for the first pallet P with the respective load C and a second extreme position in which the gripping member 3 is superimposed on a second site 13 for a second pallet B.
  • the lifting member 17 of the device 1 is assigned to translate the second pallet B vertically or parallel to the vertical direction z from the second site 13 up to a height equal to or slightly lower than the predetermined maximum height.
  • the translating member 9 positions the walls 5 of the gripping member 3 on the lateral sides of the upper portion of the load to be separated from the rest of the underlying load C of the first pallet P, where this portion to be separated consists of one or more upper layers of parcels or boxes of the load C.
  • the gripping member 3 tightens the walls 5, gripping said portion of the load and the translating member 9 lifts the gripping member 3 with the load portion and translates it laterally above the second site 13.
  • the lifting member 17 raises the second pallet B to a height equal to or slightly lower than that of the lower part or lower face of the load portion above the second site before said translation of the load portion above the second site; in this way when the load portion is translated laterally it is always slightly higher than the height of the second pallet B and therefore, even if a collapse or deformation of the boxes of the load portion were to occur, they would find a support immediately underneath them consisting of the top of the remaining load and/or in the second pallet which therefore prevents the complete collapse and falling of the parcels of the handled load portion.
  • the translating member 9 descends or the lifting member rises until it brings the second pallet into complete contact with the lower part , i.e. with the lower face, of the removed load portion which is then released by the gripping member 3.
  • the lifting member then lowers the second pallet B with said load portion up to the second site 13 where it can be picked up, as illustrated in figure 8 or wait for further cycles to place on the second pallet B the upper portions to be removed from further and subsequent first pallets P as illustrated in figures 8-11.
  • the upper face of the second pallet B can be brought to the height of the ideal horizontal separation plane of the portion to be separated from the remaining load or a few millimetres below such plane and the walls 5 can be placed close to the sides of the load portion to be separated, without the need to tighten them, and the translating member 9 can translate the gripping member one wall of which will push the load portion, making it slide over the remaining load up to the second pallet B, therefore without necessarily tightening and lifting the portion.
  • the lifting member 17 lowers the second pallet B and the load portion for withdrawing it or for other cycles, as seen previously.
  • the gripping member 3 is provided with a body 25, for example in the shape of a plate, trellis or lattice truss, supporting one or more, preferably two, first guides 21 parallel to the horizontal direction x.
  • both walls 5 of the gripping member 3 are slidably connected to such first guides 21 and operated along the latter 21 by respective actuators 23.
  • the gripping member 3 can be provided with a fixed wall 5 and a wall 5 slidably connected to such first guides 21 and operated along them by a respective actuator 23.

  • the translating member 9 comprises a horizontal beam element 31 carrying a first carriage supporting the body 25 of the gripping member 3 and operated along at least a first translation guide 33, parallel to the horizontal direction x, by a respective actuator.
  • the translating member 9 also comprises a vertical beam element 35 carrying a second carriage fixed to the horizontal beam element 31 and operated by a respective actuator along at least a second translation guide 37, parallel to the vertical direction z and preferably fixed to the vertical beam element 35.
  • each of the horizontal and vertical beam elements carries two respective guides.
  • the lifting member 17 comprises a vertical column element 41 carrying a third carriage 40 provided with forks 42 or other support for the second pallet B.

  • the third carriage 40 is connected to the forks 42 in a rigid or adjustable way to adapt it to second pallets of different sizes.
  • Said third carriage 40 can be provided with at least one optional horizontal movement element, driven to cause one side of the second pallet B to abut a side of the load C immediately underneath the upper portion of the load to be separated immediately before and during the movement of such load portion carried out by the gripping member 3 and translating member 9.
