Definitions

  • the present invention relates to a liquid filling nozzle for use in filling a liquid, such as flowable food, into containers.
  • filling nozzles are usable free of any problem for free-flowing liquids such as milk but encounter difficulty in handling at a high speed liquids, such as fresh cream and yoghurt, which are low in flowability since such a liquid is not dischargeable from the nozzle quickly and can not be cut sharp, whereas the present applicant has already proposed a nozzle by which even a liquid of low flowability can be filled into containers at a high speed free of trouble like free-flowing liquids.
  • the proposed nozzle comprises a tubular nozzle main body, a damper attached to the lower end of the nozzle main body and movable upward and downward, a spring suspending member fixedly provided within the main body at an upper portion thereof, a coiled spring suspended from the suspending member, a member connecting the lower end of the spring to free ends of the damper, and a resistant member secured to the connecting member and positioned below the coiled spring for acting against a downwardly flowing liquid.
  • the nozzle When a liquid is forced into the filling nozzle, the liquid pressure acting on the damper opens the damper against the force of the coiled spring, while the liquid pressure on the resistant member also acts to open the damper, opening the damper correspondingly to a greater extent. Consequently, the liquid flows out of the nozzle main body quickly without permitting formation of air bubbles due to agitation of the liquid that would occur at a low flow rate.
  • the nozzle is adapted for a high-speed filling operation.
  • the main object of the present invention is to provide a filling nozzle for filling a liquid into containers at a higher speed than the foregoing nozzle.
  • the liquid filling nozzle of the present invention comprises a vertical tubular nozzle main body, a damper attached to the lower end of the nozzle main body and pivotally movable upward and downward, a resistance member extending within the nozzle main body and being movable upward and downward, a member connecting free ends of the damper to the resistance member, and a resilient member biasing the resistance member upward as known from EP-A-0 138 234.
  • the nozzle main body has a reduced diameter portion at an intermediate portion of its height, the arrangement being such that from the rest position where the resistance member is positioned in said reduced diameter portion the resistance member during liquid flow will be shifted in a downward direction to such extent that it leaves said reduced diameter portion.
  • Figs. l and 2 show a liquid filling nozzle which is connected to a filing cylinder ll of a filling machine, with a check valve l2 provided therebetween.
  • the nozzle comprises a vertical tubular nozzle main body l4 having a reduced diameter portion l3 at an intermediate portion of its height, a damper l5 attached to the lower end of the main body l4 and pivotally movable upward and downward, a resistance member l6 extending within the main body l4 from the reduced diameter portion l3 to a portion therebelow and movable upward and downward to act against a downwardly flowing liquid, a guide member l7 for guiding the upward and downward movement of the resistant member l6, a connecting member l8 connecting the free ends of components of the damper l5 to the resistant member l6, and a resilient member l9 biasing the resistant member l6 upward.
  • the nozzle main body l4 comprises an upper member 2l, an intermediate member 22 and a lower member 23.
  • the upper member 2l comprises an upper-end large diameter portion 25, an intermediate portion 26 having an increasing diameter upward, and a lower-end small diameter portion 27.
  • the large diameter portion 25 is equal in inside diameter to the filling cylinder ll and is provided with a flange 28 around its upper end.
  • the nozzle main body l4 is connected to the filling cylinder ll with a flanged nut 29 which is screwed on an externally threaded portion 3l at the lower end of the cylinder ll, with the flange 30 of the nut 29 engaged with the flange 28 from below.
  • the lower-end small diameter portion 27 has a flange 32 therearound at an intermediate portion of its height. Under the flange 32, the small diameter portion 27 includes a spigot 33 having a uniform diameter and a smooth-surfaced outer periphery. An annular groove 34 is formed in the outer surface of the spigot 33.
  • the intermediate member 22 comprises an upper-end small diameter portion 36, an intermediate tapered portion 37 having an increasing diameter downward and a lower-end large diameter portion 38.
  • the small diameter portion has a smooth inner surface and provides a socket 39 with the spigot 33 fitted therein.
  • the small diameter portion 36 is formed with slits 40 opposed to the annular groove 34 in the spigot 33.
  • a retaining ring 4l is fitted in the groove 34 through the slits 40, whereby the spigot 33 is prevented from slipping off from the socket 39.
  • a rotation preventing pin 42 is implanted through the flange 32 of the small diameter portion 27 of the upper member 2l in the upper end of the small diameter portion 36 of the intermediate member 22.
  • the lower-end small diameter portion 27 of the upper member 2l and the upper-end small diameter portion 36 of the intermediate member 22 provide the overall reduced diameter portion l3 of the nozzle main body l4.
  • the lower-end large diameter portion 38 is externally threaded as at 43.
  • the lower member 23 comprises a circular upper tubular portion 45 and a quadrilateral lower tubular portion 46.
  • the upper tubular portion 45 is approximately equal in diameter to the lower-end large diameter portion 38, of the intermediate member 23.
  • the upper tubular portion 45 is internally threaded as at 47 and has screwed therein the externally threaded lower end 43 of the intermediate member 22, whereby the lower member 23 is joined to the intermediate member 22. With these members thus joined together, a flange 48 on the inner surface of the circular tubular portion 45 is at a small distance away from the lower end of the intermediate member 22.
  • the lower tubular portion 46 has at its lower end a quadrilateral edge defining an opening. Two inverted trapezoidal guide plates 49 opposed to each other extend downward from two opposed sides of the quadrilateral edge.
  • the damper l5 comprises a pair of hingedly openable plates 5l provided between the two guide plates 49.
  • Each of the openable plates 5l comprises a quadrilateral bottom wall 52, and a pair of triangular side walls 53 extending upright from the opposite edges of the bottom wall.
  • the bottom wall 52 is secured at one end thereof corresponding to the base portion of the plate 5l to a horizontal pin 54.
  • the horizontal pin 54 is rotatably supported at its opposite ends by the upper edges of the guide plates 49 each at the corresponding end thereof.
  • each side wall 53 of the plate 5l is in sliding contact with the inner surface of the guide plate 49 opposed thereto.
  • An upward lug 55 is centrally formed on the upper surface of the bottom wall 52 of each openable plate 5l.
  • a hole 56 is formed in the lug 55.
  • the resistant member l6 is in the form of a mushroom and comprises a vertical stem 6l and a horizontal disklike head 62 secured to the upper end of the stem 6l.
  • the lower end of the stem 6l is in the form of a vertical plate formed with a hole 63.
  • the head 62 has a central bore 64 through which the upper end of the stem 6l is inserted.
  • a retaining ring 65 is fitted around the upward porjection of the stem 6l above the head.
  • the upper surface of the head 62 is frustoconical.
