Definitions

  • the invention relates to the industrial field of machines, plants and/or device for working, treatment and packaging of vegetable and fruit products destined for large-scale distribution.
  • the present invention relates to packaging articles and/or vegetable and fruit produce, such as for example modest-sized and substantially spherical fruits (apples, oranges, mandarins and the like) internally of suitable containing crates.
  • packing fruit, and in particular apples, in crates is generally done using special trays made of a flexible material or a non-flexible material provided with a plurality of cells for ordered housing of the fruit to be packed.
  • machines are known in which the packing of the apples is done by special machines comprising a combined line advancement system for the fruit, trays and crates, each of which lines is supplied by a respective loading station.
  • the fruit advancing lines and the celled trays are superposed and converge at a terminal zone of the advancement line of the fruit, so that the fruit is arranged by force of gravity onto the underlying cells of the trays.
  • the advancement line of the trays extends beyond the convergence zone to constitute a further advancement line dedicated to the advancing of the trays filled with the supplied fruit.
  • the advancement line of the filled trays superposes the advancement line of the containing crates up to a convergence zone corresponding to a terminal zone of the advancement line of the filled trays.
  • the arrangement of the celled trays in the crates is achieved substantially by a combined effect of sliding and positioning by force of gravity.
  • the station the operation is performed at comprises in substance two transport planes, one superposed on the other, and suitably synchronised.
  • the crates are conveyed on the lower plane and the trays containing the fruit on the upper plane. Thereafter, at the terminal edge of the upper plane, the trays are deposited internally of the crates which run below them.
  • the crates are rest on a tilting support plate hinged at a transversal axis with respect to the lower transport plane.
  • the crate is arranged on the support with the posterior wall thereof (the wall arranged downstream with respect to the advancement direction of the conveyor belt) in proximity of the hinge axis of the support.
  • the inclined position of the crates enables the strike point between the front wall and the bottom surface of the crates to be in proximity of the end edge of the upper transport plane. In this way, when the front portion of a tray leaves the upper transport plane it is deposited in a front zone of the crate.
  • the upper and lower transport planes move substantially at a same speed in order to enable a correct positioning of the trays in the crates.
  • Packaging lines of known type exhibit some drawbacks.
  • the depositing of the trays internally of the crates is frequently obstructed and made imprecise by friction forces that are created between the edges of the trays and the walls of the crates.
  • the main aim of the present invention is to obviate the drawbacks of packaging lines of known type, by providing a positioning device for depositing trays internally of crates, which places the trays correctly without any need for further intervention.
  • An advantage of the present invention is that it is easily applicable to packaging lines for vegetable and fruit produce already used in the sector.
  • 2 denotes a machine 2 for packing articles 3, in particular vegetables and fruits of overall modest size and being substantially spherical or rounded, such as apples, oranges, mandarin oranges and the like.
  • the machine 2 comprises a first loading station 4 for infeeding trays 5 each of which exhibits a structure 6 which is substantially flat, and at least a cell 7, advantageously a plurality of cells 7, for ordered housing of single vegetables or fruits 3 to be packed in special crates 8.
  • the first loading station 4 supplies the trays 5 to a first advancement line 9 which extends preferably by a side of the first loading station 4 along a substantially straight direction A which is the advancement direction of the trays 5.
  • the first advancement line 9 comprises at least a conveyor belt 10 which extends horizontally along the above-mentioned advancement direction A.
  • the first advancement line 9 can be realised using any other conveyor suitable for advancement of the trays 5.
  • the machine 2 comprises a second loading station (not illustrated in the figures of the drawings) which is deputed to supplying the above-mentioned vegetables or fruits 3 to be placed in the cells 7 of the trays 5.
  • the second loading station provides a continuous supply of fruits 3 to be packed to a second advancement line 11 which extends preferably in a substantially straight direction, advantageously coinciding with the advancement direction A of the trays 5 along the first advancement line 9.
  • the second advancement line 11 is preferably superposed on the first advancement line 9 so that the fruit articles proceed, substantially parallel, above the trays 5.
  • the second advancement line 11 includes the use of a conveyor 12, partially constituted by rollers, which develops horizontally above the conveyor belt 10 of the first advancement line 9, to facilitate the advancement of the fruits 3 launched from the second loading station.
  • the first and second advancement lines 9, 11, converge to one another along the advancement direction A in order to perform the housing of the fruits 3 in the cells 7 of the trays 5 being supplied.
  • the first advancement line 9 exhibits an inclined tract 9a which develops from the belt 10 and terminates approximately at the same level as the roller conveyor 12 of the second advancement line 11.
