Definitions

  • the present invention relates to an automatic device for container packaging machines which is designed to perform gripping and holding of flexible bag-shaped containers during the entire packaging cycle, said device being provided with means independent of one another for adjusting the relative distance of each gripping element with respect to the vertical axis of symmetry of the container itself.
  • the upper part of the said containers is shaped in widely varying forms so as to provide for example handles, bottle-necks and the like, this variety of configurations which may also be asymmetrical with respect to the vertical axis of the container requiring the replacement of the known gripping devices which do not envisage independent adjustment of the distance of the gripping elements with respect to the said axis of symmetry.
  • the technical problem which is posed, therefore, is that of providing a device for gripping and holding containers in the form of a bag or the like made of flexible material, which is suitable for coupling to means for transporting the containers themselves inside packaging machines and operation of which can be effected by means of suitable elements integral with the machine so as to achieve holding of the containers and facilitate opening/closing of the mouth thereof during the various stages of packaging.
  • the gripping elements should be able to perform a translatory movement, independently of one another, with respect to the axis of vertical symmetry of the container so as to ensure carrying out of the said gripping, opening and closing operations also for containers which are asymmetrical and have different widths, without the need for replacement of the entire unit.
  • gripping devices should be easy and economical to install and be able to be supplied by means of suitable container loaders coupled to the machine.
  • an automatic device for gripping and holding containers in the form of a bag or the like made of flexible material in particular for automatic packaging machines which comprises two pincer-type gripping units located opposite one another and independent of one another, each of which is mounted on an associated upright integral with a base and movable in translation on the base itself with respect to the axis (X-X) of vertical symmetry of the container, said gripping units being operated so as to perform a synchronized rotation away from and towards said axis of symmetry via first operating means, cooperating with means integral with the packaging machine, and so as to open and close via second operating means, cooperating with associated means integral with the machine and acting against the recall action of elastic elements, said first and second actuating means causing the symmetrical movement of the pincers towards/away from the axis (X-X) of vertical symmetry of the container and closing/opening of the pincers themselves in order to hold the container and cause opening/closing of the mouth thereof during the filling and sealing phases.
  • the automatic gripping device 1 comprises a substantially flat support base 2 integral with a shank 2a of square cross-section extending underneath the said base 2 and fixed to a disc 101 rotating about an axis of rotation 101a of a packaging machine shown only schematically by 100.
  • the upper surface of the base 2 has mounted on it travel rollers 2a designed to engage with the opposite surfaces of a guide rail 102a integral with a fixed disc 102 of the machine 100: in this way the gripping devices 1, arranged at predetermined angular distances on the rotating disc 101, are able to rotate together with the latter, travelling on the fixed guide 102a and passing underneath the various stations of the machine 100.
  • the edge of the base 2 which is external with respect to the axis of rotation of the machine 100 is formed in the manner of a dovetail cross-section 2b onto which are inserted the bottom ends of a fixed central upright 4 and two lateral uprights 5 which slide independently of one another on the dovetail 2b and can be locked on the latter in different positions.
  • the central fixed upright 4 is shaped in the manner of an upturned “U” and the internal short branch of the "U” directed downwards is formed by small cylinders 4a, the bottom free end of which terminates in end-of-travel discs 4b for a horizontal rail 6 sliding in the vertical direction on the said small cylinders 4a actuated by cam means 106 integral with the machine 100 and designed to come into contact with a roller 6a mounted on an arm 6b extending from the rail 6 towards the axis of rotation of the machine.
  • the rail 6 On the outer side the rail 6 has a C-shaped cross-section designed to form the guide 6c for travel of a roller 8a described in more detail below.
  • Each lateral upright 5 supports a horizontal hollow shaft 7: the internal end of said hollow shaft is connected to a rotational actuating arm 8, the free end of which has mounted on it the said roller 8a travelling on the said rail 6.
  • the external end of the hollow shaft 7 carries, on the other hand, the unit 9 forming the actual pincer.
  • the hollow shaft 7 has arranged inside it, coaxially with respect thereto, a rod 10 free to slide relative to the hollow shaft 7 and pushed by a cross-piece 11 actuated by cam means 111 integral with the machine 100 against the recall action of elastic means 12 described more fully below.
  • the external end of the rod 10 terminates in a base-piece 10a, while at the internal end of the rod 10 there is arranged a block 14 provided with an inclined-surface tooth 14a designed to cooperate with a corresponding and complementary projection 15a of a rocker element 15 rotatable about a horizontal pin 15b against the thrusting action of a resilient lamina 15c.
  • the external end of the hollow shaft 7 carries the pincer unit 9 substantially consisting of a horizontal arm 16 intergal with the hollow shaft 7 with which it is able to rotate and carrying on the opposite side a vertical block 17 externally shaped so as to form the fixed jaw 17a of the pincer.
  • the block 17 has housed inside it a spindle 18, the opposite ends of which have fixed to them, respectively, an upper and lower horizontal arm-piece 18a and 18b forming the movable jaws of the pincer and the associated means for transmission of the closing/opening movement imparted, as described in more detail below, via the rod 10 and the base-piece 10a.
  • the bottom arm-piece 18b has hooked to it one end 12b of the said spring 12, the other end 12a of which is hooked to the bottom part of the arm 16.
  • the lateral uprights 5 are arranged symmetrically with respect to the axis of symmetry X-X of the bag and at a suitable distance from one another.
  • the disc 101 conveys the bag to the filling station and before the travel has been completed opening of the mouth 20a of the bag is obtained (Figs. 5a, 5b) by means of further lowering of the rail 6 until it comes up against the end-of-travel stop 4b, this lowering movement causing a further rotation of the arms 8 and hence the arms 16 which bring the pincers 9 into the position where they are located at a mininum relative distance with respect to the axis X-X of symmetry of the bag, forcing the latter to open.
  • the disc 101 must convey the bag to the sealing and the unloading points and therefore the pincers will be actuated during this travel section in accordance with a sequence exactly opposite to that described above in order to obtain reclosure of the mouth 20a for sealing thereof and opening of the pincers for removal of the bag 20 by a loader not shown.
  • bags 120 which are asymmetrical, for example on account of a lateral chamfer 120b: in this case it is sufficient to slide the corresponding lateral upright 5 on the dovetail 2b of the base 2 until it is brought into the appropriate position closer to the axis of symmetry X-X of the bag 120 itself.
  • the device according to the invention allows bag-shaped containers of the most varied shapes and sizes to be handled automatically without having to provide special pincer configurations for each type, thus avoiding production downtimes associated with retooling of the packaging machine.
