Definitions

  • the invention relates to a method and apparatus for producing glass ampoules in particular double ampoules which comprises drawing an elongated thin neck into a glass tube at a distance from the end of the tube corresponding to the length of one ampoule body.
  • the neck is twice the normal length of an ampoule neck and is later divided in the middle.
  • At a distance from the end of the neck equal to the length of a second ampoule body at least one ampoule is melted off from the tube and simultaneously each ampoule bottom is closed.
  • During drawing of the ampoule neck that portion of the double neck where separation is to be effected, is cooled, to form a funnel-shaped end on each single length neck.
  • the invention relates to a method of producing ampoules, particularly double ampoules, which comprises drawing an elongated thin neck into a glass tube at a distance from the end of the tube corresponding to the length of one ampoule body, said neck being twice the normal length of an ampoule neck and being later divided in the middle, and at a distance from the end of the neck equal to the length of a second ampoule body melting off an ampoule or double ampoule from the tube with the simultaneous closing of the ampoule bottoms.
  • the proposed method has the advantage of being extremely economical to perform, a circumstance of considerable importance, bearing in mind that ampoules are mass produced articles.
  • a preferred apparatus comprises an upper and a lower rotating chuck of which at least one is movable to and fro for drawing an ampoule neck.
  • an assembly consisting of at least two burners of which the firstserves for forming one part and the second the other part of the double length neck, and of a blowing nozzle for blowing cold air intermediately between the two burners.
  • the filling funnels at the ends of the ampoule necks are not produced by expanding. the weekends, as was hitherto the practice, but bypreventing the corresponding portion of the double neck from being drawn down during the process of production of the ampoule respectively double ampoule. Hence two filling funnels are formed simultaneously with the production of the double ampoule neck.
  • FIG. 1 is apparatus in a first operative position for performing the method according to the invention
  • FIG. 2 is a view of the apparatus in FIG. 1 from above and FIG. 3 is the apparatus in FIG. 1 in a second operative position.
  • a glass tube 11 is held between the jaws 12 of an upper rotating chuck l3 and of a lower rotating chuck 14.
  • the latter chuck 14 is is also adapted to be lowered and raised as indicated by an arrow 15.
  • the rotary movement of both chucks is in the direction indicated by an arrow 16.
  • both chucks bodily travel along a circular path 17 indicated in FIG. 2 by an arrow 18. In the course of this latter motion they pass different working stations.
  • a swivel arm 19 is adapted to swing about a hinge 20 at the end of a swing arm 21 attached by a pin 22 to part 23 of a glass working machine.
  • the swivel arm 19 carries rollers 24 which bear against the circumference of the upper chuck 13 with which they are kept in contact by springs not shown in the drawing.
  • Fast with the swivel arm 19 is a rod 25 containing splines 26 engaged by a bush 28 which can rise and fall on the rod without rotating.
  • the bush carries three pipes 29,30 and 31, of which pipes 29 and 31 are connected to supply pipes 32 and 33 providing a mixture of gas and air, whereas pipe 30 is connected to a supply pipe 34 for cold air.
  • the end of the pipes 29 and 31 facing the glass tube 11 are each fitted with a burner 35 and 36, whereas the end of pipe 30 carries a blower nozzle 37.
  • portions 38 and 39 of the glass tube 11 are heated by the flames of the burners 35 and 36, whereas portion 40 is cooled by the cold air issuing from the blowing nozzle 37.
  • the chuck l5 and the bush 28 together with their associated parts jointly descend.
  • the heated portions 38 and 39 of the glass tube are thus elongated so that they assume the shape illustrated in FIG. 3. Since portion 40 of the glass tube cannot be deformed by the cold air issuing from the blowing nozzle 37, the tube here retains its original diameter.
  • the necks of two ampoules will have been formed.
  • the glass tube is allowed to slip a predetermined distance downwards in a manner known in the art and the double ampoule is separated by melting it off with the simultaneous formation of the bottom of the upper ampoule and of the bottom of the following lower ampoule.
  • the burners 35, 3,6 and the blowing nozzle 37 participate in the downward movement of the chuck 14 during its descent.
  • a method of producing ampoules, particularly double ampoules which comprises drawing an elongated thin neck into a glass tube at a distance from the end of the tube corresponding to the length of one ampoule body, said neck being twice the normal length of an ampoule neck and being later divided in the middle, and, at a distance from the end of the neck equal to the length of a second ampoule body, melting off at least one ampoule from the tube with the simultaneous closing of each ampoule bottom, characterised in that during the drawing of the ampoule neck that portion of the double neck where separation is to be effected is cooled to form a funnel-shaped end on each single length neck.
  • Apparatus 'for producing double ampoules comprising an upper and a lower rotating chuck, of which at least one is movable to and fro for drawing an ampoule neck, characterised in that, for forming a doublelength neck, an assembly consisting of at least two burners is provided, of which the first serves for forming one part and the second the other part of the double length neck, and in that a blowing nozzle blowing cold air is located interrnediately between the two burners.
