Definitions

  • This invention relates to a method of and apparatus for orientating an annular element, for example a flange of a pour spout of a pour spout fitment.
  • Two-and three-part pour spout fitments of thermoplastics are known for applying to liquid packaging cartons comprised of plastics-coated paperboard.
  • fitments are subsequently supplied loosely to hoppers at packaging machines, for example filling machines, whence they are fed by way of chutes to fitment applicators of the machines. Certain designs of fitments need to be orientated for correct application to the respective cartons.
  • a method comprising producing pressing force between a member and the outer periphery of an annular element, producing relative rotary motion, about the axis of said element and between said element and said member in contact with said periphery, until said periphery allows or causes relative movement between said element and said member towards or away from said axis, detecting said relative movement, and thereupon ceasing said producing of said relative rotary motion, thereby to orientate said element.
  • apparatus comprising a mounting device for supporting an annular element, a follower member, a drive arrangement serving to produce relative rotary motion, about an axis, between said mounting device and said member, a biassing device arranged to urge one of said mounting device and said member towards the other transversely of said axis, and a detection device arranged to detect relative movement between said mounting device and said member under the action of said biassing device and thereupon to cause said drive arrangement to stop said relative rotary motion, thereby to orientate said element.
  • a method comprising supplying a pour spout fitment, producing pressing force between a follower and an annular surface of said fitment, producing relative rotary motion, about the axis of said surface and between said surface and said follower in contact with said surface, until said surface allows or causes relative movement between said member and said surface transversely of said relative rotary motion, detecting that the latter relative movement has been allowed or caused, thereupon ceasing said producing of said relative rotary motion, and thereafter applying the thereby orientated fitment to a container.
  • apparatus comprising a device for supplying a pour spout fitment having an annular surface, a mounting device for supporting said fitment, a follower, a drive arrangement arranged to produce relative rotary motion, about an axis, between said mounting device and said follower, a biassing device arranged to urge one of said mounting device and said follower towards the other, and a detection device arranged to detect relative movement between said mounting device and said follower under the action of said biassing device and thereby to cause said drive arrangement to stop said relative rotary motion.
  • annular elements in particular flanges of pour spouts of pour spout fitments, identically to each other in preparation for further handling or processing thereof.
  • FIG. 1 is a diagrammatic, perspective view from above of part of a form-fill-seal packaging machine
  • Figure 2 is a diagrammatic top plan of a modified version of that part.
  • Figure 3 is a view similar to Figure 2 of a unit included in that part.
  • the machine part shown includes a vertical chute 2, by way of which per se known pour spout fitments 4 are fed vertically to an escapement 6 having a singulating position 8, an orientating position 9 and a transfer position 10, whence they are transferred, one-by- one, to a recess in the active end of an ultrasonic horn or to a fitment holder of a hot seal system, for application to the outside of a carton, so that each fitment 4, as it is received in the transfer position 10, is expelled therefrom by a piston-and-cylinder transfer device 12 into the recess in the ultrasonic horn or onto the fitment holder.
  • Each fitment 4 comprises a screw cap 4A connected by tamper- evident bridges 4B to a ring 4C which encircles a pour spout 4D having an external screwthreading which co-operates with internal screwthreading of the cap 4A, external projections 4E of the spout 4D which engage among the tamper-evident bridges 4B, and an annular, end flange 4F formed with an orientation notch 4G at a location around the periphery thereof.
  • the orientation notch AG has already been employed in orientating the pour spout 4D relative to the screw cap 4A during assembly of the fitment 4.
  • a cup-form plunger 14 which is of an internally frusto-conical form at its leading end and which is displaced from a retracted position, where it is out of the path of dropping of a fitment 4 from the singulating position 8, into an advanced position in which its frusto- conical surface centres the fitment 4 relative to the axis of the plunger 14.
  • the corresponding reciprocatory motion of the plunger 14 is indicated by the double-headed arrow 16 and produced by a fluidic, piston-and-cylinder driving device 18. Singulating at the position 8 is achieved by means of per se known, horizontally reciprocatory rods 20.
  • a pin 22 Extending substantially parallelly to the axis of the plunger 14 and biassed radially inwards with respect to the axis of the plunger 14 is a pin 22.
  • the outer end of the pin 22 is movable (by means not shown) radially inwardly and outwardly relative to that axis, as indicated by the double arrow 24.
  • the plunger 14 is rotated about its own axis until the outer end of the pin 22 drops radially inwardly into the notch 4G, so signalling to a control system that the particular fitment 4 has been correctly orientated before being dropped into the transfer position 10.
  • the plunger 14, the pin 22 and the pin (not shown) against which the fitment bears downwardly in the orientating position 9 are withdrawn, so that the orientated fitment can drop into the transfer position 10 so that, when it is applied to the recess in the horn, it is correctly orientated for being applied to the exterior of a packaging carton.
  • the pin 22 is shown to be in the character of a lever-form latch 22' mounted on a pivot 28 and urged towards the fitment 4 by a helical compression spring 30 acting between a mounting bracket 32 and the latch 22' .
  • One end 22a of the latch 22' is of a wedge form so that movement of the bracket 32 towards the chute 2 under the action of the device 18 causes the end 22a to ride onto the outer periphery of the flange 4D of the fitment 4.
  • the opposite end 22b of the latch 22' is associated with an inductive sensor 34, such that, upon the end 22a dropping into the notch 4G, the sensor 34 transmits that information to the control system.
  • the device 18 moves the latch 22' towards the chute 2, it also carries with it the plunger 14, which has not only a frusto- conical centering surface 14a but also pressure-equalisation holes 14b in the base of the cup-form plunger 14 to prevent retention of the fitment 4 therein by a vacuum effect and thereby to prevent the plunger 14 from pulling the fitment out of the chute 2.
  • the motor 26 which serves to rotate the plunger 14 is connected thereto by a key arrangement 36 permitting actual sliding movement of the plunger 14 relative to the motor 26.

Abstract

L'invention concerne un appareil d'orientation pour ensemble de bec verseur (4) muni d'une bride annulaire (4F). Ledit appareil comporte un dispositif de montage pour supporter l'ensemble (4) ; un suiveur (22) ; un dispositif d'entraînement agencé pour produire un mouvement de rotation relatif, autour d'un axe, entre le dispositif de montage et le suiveur (22) ; un dispositif de sollicitation agencé pour solliciter le suiveur (22) vers le dispositif de montage ; et un dispositif de détection agencé pour détecter un mouvement relatif entre le dispositif de montage et le suiveur (22). Causé par l'action du dispositif de sollicitation et permis par une encoche (4G) pratiquée dans la bride (4F), ledit mouvement amène le dispositif d'entraînement à arrêter le mouvement de rotation relatif et à orienter l'ensemble (4).
