Definitions

  • the present invention refers to the field concerning the palletized packaging and in particular refers to a machine for carrying out palletized packagings.
  • a drawback of such known devices consists in that they are not able to carry out a packaging comprising a completely wrapped load and comprising a support means consists of a single pallet or of a multiple elements pallet, where said pallets are fixed to the mentioned load.
  • One object of the present invention is to propose a machine for carrying out in semiautomatic or automatic way palletized packaging completed of a fully wrapped load and of a support means consists of a single or in multiple elements pallet, fixed to the load.
  • Another object is to propose a relatively cumbersome and inexpensive machine.
  • Further object is to propose a machine which allows to use pallets of multiple type or rather carried out with separate elements that form the pallet when they are fixed to the load; and pallet in a single body or already assembled, or rigid or flexible pallets.
  • 1 indicates the machine for carrying out palletized packaging, object of the present invention, starting from a load C consisting of a set of stacked or overlapped packages or the like and by support means S consisting of pallet constituted by multiple and flexible supports or rests.
  • the machine 1 comprises at least a wrapping device 100, a film rolling device 101 placed downstream of the wrapping device 100 and an inserting device 102, 103 interposed between the wrapping device 100 and the film rolling device 101.
  • the load C consisting of a package or in a set of stacked packages, is formed, or rather stacked, on an inlet conveyor means 14 of the wrapping device 100, or upstream of such inlet conveyor means and transferred onto it.
  • the inlet conveyor means 14 can be associated with an optional wrapping arm device 15, for example of known type, for wrapping the load in horizontal coils of packaging film.
  • the wrapping device 100 comprises a wrapping means 3 placed downstream of the optional inlet conveyor means 14, which feed it with the set of packages possibly wrapped at horizontal coils.

  • the wrapping means 3 can move the set of packages C on a horizontal plane along its longitudinal direction in both feed directions, from the inlet toward the outlet, and vice versa in the withdrawal direction.
  • upper and lower are referred to the horizontal moving plane; the terms front and rear refer to the feed or forward direction and withdrawal or back refers to the backward direction, from the outlet to the inlet of the device.
  • the wrapping means 3 is provided with a wrapping machine, for example of known type, comprising a reel means 4 for the unwrapping of a coil of packaging film B and moved by annular rotation means 5 along an circular path that in the operating condition of the device it develops on a vertical or almost vertical geometric plane.
