Definitions

  • This invention relates to the technical field concerning the packaging of orderly groups of containers into cartons.
  • some packaging machines are provided with devices having the purpose of checking the height of the piles of containers being sent to the packaging section; the check is usually carried out through special level-sensing means, or means to sense the beginning and/or the end of groups of containers.
  • the wrong positioning is related to the axial displacement of two containers along the conveying line (fig. 5); or it may be due to the arrangement of a container in an inclined position (fig.6); or it may be caused by the rotation of a container that does not keep the proper conveying position (fig.7).
  • the objects of the present invention is to provide a device that makes it possible to check the actual presence of all the containers provided in the orderly piles that are to be packaged by a special machine.
  • Another object of the present invention is to provide a device to check the presence of containers to be packaged, obtained through a technical solution which is simple, functional and reliable, as well as of versatile use.
  • a device for checking the presence of containers to be packaged characterized in that it comprises a plurality of feeling means supported in such a way that they can swing around a vertical axis and located beside means for conveying the piles of containers to be packaged, said feeling means moving from a rest position, where they result to protrude at one end over said conveying means, to an activated position, wherein they laterally slide against said containers, and vice-versa.
  • sensing means provided for sensing the rotation of said feeling means between said rest position and said activated position.
  • the numeral 1 generally designates the device to check the presence of containers 2 to be packaged.
  • the containers 2, arranged in orderly piles 20, are fed by conveying means 3 provided with a pushing means 4; the pushing means 4 carries out the advance of a predetermined group of piles 20, arranged close to each other along the conveying line and guided between two side walls 5, to a packaging station 6.
  • the transferring means 7 is operated in the direction B transverse to the conveying line of the means 3.
  • the check device 1 is provided with a plurality of feeling means 8, which are swingingly supported around a vertical axis 9 beside the conveying means 3.
  • the feeling means 8 consist of lamellar rods arranged on horizontally adjacent planes, so as to intercept respective containers 2 arranged in a pile; it is usefully provided for each container 2 of the pile to be interested by at least two feeling means 8.
  • the feeling means 8 are able to swing between a rest position in which they result to face each other with the free end inside the conveying line, through an opening 10 made in a wall 5, close to the outlet of the conveying means 3; and an activated position, rotated outside the conveying line, in contrast with respective spring means 11.
  • the device 1 also comprises sensing means 12 and 13 which are suited to act at the rear end of the feeling means 8, respectively close to the rest position 8a and to the activated position 8b.
  • the sensing means 12 and 13 consist of respective pairs of photoelectric sensors, respectively transmitters and receivers, and they are connected to suitable checking means of the machine, not illustrated.
  • the device operates as follows.
  • the group of piles 20 of containers 2 to be packaged advances along the conveying line defined by the means 3 and it is pushed into the packaging station 6, as indicated by broken line 14, where the transferring means 7 provide for pushing it into the carton.
  • the containers 2 When passing close to the opening 10, the containers 2 strike laterally against the end of the feeling means 8, causing them to rotate from the rest position 8a to the activated position 8b.
  • the sensing means 12, 13 are able to sense said rotation of the feeling means 8 and consequently to signal the passing of the piles 20 of the containers 2 to be packaged.
  • a position 8c is transitorily determined, wherein both sensing means 12 and 13 result to be activated, since said feeling means are disposed in an intermediate position between the same sensing means.
  • Said transitory position 8c is suited to supply the signal to start the operation of the check device.
  • An analogous transient signals the end of the passing of the piles 20 to be packaged.
  • the check device In case of absence of one or more containers 2 in the piles 20, the check device provides to signal the gap. In fact, when a gap passes in front of the check device, the feeling means located on the plane where said gap occurs are sent back to the position 8a by the relative spring means 11, deactivating the sensing means 12. The contemporary deactivation of the sensing means 12 and 13 signals the irregularity of the pile.
  • the feeling means 8 are able to signal the gap in any zone it occurs, even in the case that the piles maintain the predetermined height.
  • fig. 15 is illustrated, by way of example, the gap occurring between two containers 2a, 2b displaced axially along the conveying line.
  • the gap is partially occupied by a container 2c disposed in inclined position; in this case, the presence of at least two feeling means for each container of the pile assures the detection of the gap.
  • the gap is caused by the rotation of a container 2d or of a whole pile transversely to the proper conveying position.
  • the feeling means 8 may either be translated as a whole, or mutually brought near and moved away from each other along the axis 9: the relative means to carry out such translations are not illustrated, since they are known.
  • the device conforming to the invention makes it possible to check the possible presence of any gap in the piles of containers to be packaged.
  • the device is operated at the beginning of the passing of the group of piles to be packaged and automatically stopped at the end of said passing, corresponding to the respective transients of the oscillation of the feeling means.
  • the sensing means 12, 13 can be of any type, particularly of electro-mechanical type, and suited, when necessary, to be associated with each feeling means 8; the data collected by said sensing means are sent to said checking means where they are "processed" similarly to what has been said above.
