Definitions

  • the invention relates to a method for moving a valve-sack from a filling position, where the sack's valve can be permanently sealed or closed, whereby the sack can be withdrawn from the filling nozzle and supported during its movement.
  • the invention also relates to an apparatus for the execution of the method, comprising a movable support element arranged for a filled valve-sack which can move the valve-sack from a filling position, where the sack's valve is applied to a filling nozzle, to a closing position where the sack's valve can be permanently sealed or closed, and a filling nozzle for use in connection with the apparatus.
  • Such a method and apparatus are known from GB publication 21 68 671.
  • the movable support element is built together with the filling nozzle.
  • the valve is held on the filling nozzle while at the same time the sack is tipped over into an inclined position, where the mouth of the valve points upwards at an angle. Thereafter, a further tipping of the sack takes place while the filling nozzle is held stationary until the valve is released from the nozzle.
  • the object of the invention is to provide a method and an apparatus whereby a positive control of the position of the valve can be effected between the filling position and the welding position, so that a greater reliability of the weldings is achieved.
  • the apparatus according to the invention is special in that the apparatus comprises two finger-shaped gripping elements which are mounted on control-arms, said control-arms being able to be moved in such a manner that the gripping ele ⁇ ments can be placed opposite each other on each side of the filling nozzle opposite the valve opening, introduced into the opening, grip the wall of the valve and move away from each other.
  • the gripping elements are introduced into the valve from the open side while the sack sits on the filling nozzle.
  • the side walls of the valve are thus under control when the valve is withdrawn from the filling nozzle, possibly during the transfer of the sack itself.
  • the gripping elements are drawn away from each other and the originally cylindrical valve opening is hereby made flat. In this condition, it is pos ⁇ sible to effect a very precise positioning of the closing elements, e.g. in the form of ultrasonic welding equipment or a glueing apparatus, in relation to the valve.
  • the filling nozzle according to the invention is provided with two pairs of ribs which lie opposite one another and which extend in the longitudinal direction of the nozzle.
  • the finger-shaped gripping elements can be inserted in the space which is formed by the ribs between the nozzle and the wall of the valve, and the insertion is therefore ef ⁇ fected with greater certainty.
  • figs. 1-3 show a filling station for a valve-sack seen from the side in three different operational steps
  • figs. 4a-b schematically show the positioning of the gripping elements in relation to the filling nozzle, and a valve-sack mounted in the start position, seen from the front and from above respectively,
  • figs. 5a-b show the same, but where the gripping elements are in engagement with the wall of the valve
  • figs. 6a-b show the same as in fig. 5, but where the valve is withdrawn from the filling nozzle
  • figs. 7a-b show the same as in fig. 6, but where the gripping elements are drawn away from each other and the valve is drawn flat, and
  • fig. 8 shows a section through an apron containing a control arm and a clamping jaw in the apparatus.
  • the filling station is configured as shown in the drawing.
  • a filling apparatus 1 with filling nozzle 2 is applied to valve-sack 3 by means of a commonly- known sack handling apparatus 4.
  • the apparatus 5 consists of a base-frame 6 which stands on the floor 7 and contains a not-shown drive and control unit.
  • a parallel-arm control arrangement is formed for a console 11 which is tipped around a horizontal axis by means of the arm 10 which comprises a compressed-air cylinder.
  • Both of the arms 8b and 9 are kinematically connected with gears inside the box 12, whereby they can move symmetrically around a vertical plane through the box 12.
  • a commonly-known ultrasonic welding apparatus 18 is secured to the frame 6 in a manner not shown.
  • the console 11 has a grid-shaped bottom 13 which can swing in under a valve-sack 3.
  • the console 11 also has two paral ⁇ lel aprons 14 which contain gripping elements or clamping jaws 15.
  • the clamping jaws are operated by compressed air and are mounted on the end of control arms 16, the con ⁇ figuration and suspension of which is shown in fig. 8.
  • Each of the clamping jaws 15 has a fixed, hook-shaped finger 21 and a compressed-air piston 30 which can clamp the wall 22 of the valve-sack against the finger 21.
  • three compressed-air cylinders 25, 26 and 27 are used in the manouevring of the arm 16, partly by swinging of a pivotable link 28.
  • the filling nozzle 2 is provided with two pairs of longitudinal ribs 19, which with regard to the use of nozzles of different sizes are secured to an annular sleeve 20. Between the ribs 19 there is room for the introduction of the clamping jaw fingers 21 between the wall 22 of the valve and the filling nozzle 2.
  • the console 11 is fed in towards the filled sack 3, which by the sack valve 23 hangs with its weight on the nozzle 2 until the aprons 14 are standing on each side of the sack 3 along the valve 17, see figs. 1 and 4a-b.
  • the bottom 13 is swung into the horizontal position, whereby the sack 3 is supported by the console 11.
  • the arms 16 with the clamping jaws 15 are fed towards each other and moved in behind the opening of the sack valve. Thereafter, the arms 16 are drawn back so that the fingers 21 of the clamping jaws engage with the wall 22 of the valve, see figs. 5a-b. The clamping jaws 15 are now activated so that the wall 22 of the valve is held.

Abstract

Appareil transférant un sac à clapet entre sa position de remplissage sur une trémie de remplissage (2) et sa position de fermeture, et comprenant deux doigts préhenseurs (15) pouvant enserrer le bord du clapet (23) faisant face à la trémie (2) des deux côtés de cette dernière (2). On peut ainsi définir avec certitude la position du clapet lorsque le sac se détache de la trémie et avance jusqu'à la position où le clapet est fermé, p. ex. par soudure aux ultrasons.
