  • This invention relates to an apparatus for placing and seam folding on aerosol containers the bottoms of dis pensing valves having tube lengths applied thereto.
  • an aerosol container carries a dispensing valve which, in turn, is mounted on the end of a tube length, the latter being inserted in the container and effective to supply the valve with the liquid withdrawn from the container adjacent the bottom portion thereof.
  • Apparatus are available for automatically placing dispensing valves integral with a metal bottom on aerosol container inlets, introducing into the containers tube lengths applied to the valves.
  • An apparatus of this type for withdrawing and placing automatically valves having different size bottoms on aerosol container inlets, without any damage either to the bottoms or to the valves, is disclosed in US. Pat. specification No. 3,604,095 assigned to the same assignee as for the present application.
  • this container movement cannot be accomplished at a high speed, since the containers are filled with liquid, while the inlet thereof is still substantially open because of the bottom being merely placed thereon. Moreover, in such cases this container transport from one machine to another, prior to tight sealing thereof, may show still more serious disadvantages should the liquid in the containers be dangerous or highly volatile.
  • an apparatus comprising a container supporting platform and a device overlying said platform and movable relative thereto, the device including a cylinder accommodating a tubular body, the latter having a cr q s s section area larger than that of the valve bottoms, and an elongated hollow body movable within said tubular body, the end of the elongated hollow body facing said platform being shaped to provide a housing seat for said bottoms and associated valves, means for provid ing air suction in said seat, retaining a valve accomodated therein, and movable means operatively connected to said tubular body and elongated body, respectively, for moving the same relative to said platform and cylinder, the apparatus being characterized by comprising seam folding pliers accommodated within said seat in the hollow body, a shaped portion of the pliers projecting therefrom, a rigid tube movable within the elongated hollow body, one end thereof extending to the proximity of said pliers, and movable means operatively
  • FIGS. 1 to 6 are partly sectional and schematic views showing the apparatus at different processing steps, FIG. 6 being drawn on an exaggerated scale and showing only the bottom portion of the apparatus.
  • an apparatus comprises a hollow cylinder 1 carried through an arm 2 by a rigid frame (not shown).
  • a rigid frame (not shown).
  • superimposed pistons 3 and 4 are sealingly accommodated and movable within cylinder 1, an axia bars a nslh shhqth of. said t ns-.,
  • An elongated hollow body 7 is fast with piston 4 and has a portion thereof downwardlyextending through the bore of piston 3 and projecting below the lower end of cylinder 1, and another portion thereof upwardly extending and carrying at its top a hollow head 8, wherein a piston 9 is housed and movable.
  • This piston is also bored and has a tube length 10 fast therewith, upwardly projecting and exiting from said head 8, and a rigid tube 11 downwardly projecting and having its lower end located adjacent the lower end of the elongated hollow body '7.
  • the lower end of said elongated hollow body 7 is shaped to present a seat accommodating therein the seam folding pliers 12, having the end thereof shaped and projecting beyond the end of the hollow body 7, the shaped end 'of pliers 12 having a crosssection of an area less than that defined by the cylindrical walls of the valve bottom, as explained in the following. ,7 h
  • a bore 13 opening in the atmosphere is formed in head 8 and other two bores are also formed which, through tubes 14 and 15, can be alternately connected to a supply of pressure fluid, such as compressed air, or to vent.
  • Bores are also formed in cylinder 1 which, through tubes l6, l7, l8 and 19 respectively (FIG. 4), can be separetely also connected to a supply of pressure fluid, for example also compressed air in this case,
  • vent can be directly communicating with vent.
  • the tube length 10 is connected to a continuously operating suction pump so that, through the cavity of rigid tube 11, air is continuously drawn from the lower end of the tube 11 and hence from the seat provided at the bottom end of the elongated hollow body 7.
  • the apparatus is carried by a rigid framework having fast therewith a bearing platform 20 for the containers 21 and a hollow element comprising a rigid portion 22 supporting two resilient blades 23, the inner surface of which defines a funnelshaped cavity, these blades being resiliently outwardly movable against the action of small springs 24.
  • While platform 20 is fast with the above mentioned rigid framework, the rigid portion 22 as well as blades 23 are carried by said rigid framework, so as to vary the distance or spacing thereof relative to platform 20.
  • the means by which said blades 23 can be carried to the rigid framework, so as to vary the distance or spacing thereof relative to platform 20, can be differently and readily provided by those skilled in the art, and therefore for brevity will not be herein described in detail.
  • the operation of the apparatus will take place by subsequent steps carried out at successive stations as the apparatus rotates about said vertical axis.
  • a container 21 is automatically loaded below the lower ends of blades 23 of a hollow element, above which the cylinder 1 is positioned.
  • valves connected to tubes 14 and 15 so as to communicate tube 15 with vent and to connect tube 14 r with the pressure air supply.
  • piston 9 is downated valves 26 and tube lengths 27, means of a known structure and ready provision being provided for placing one valve at a time below cylinder ll, means therefore not described for the sake of brevity and because not forming a part of the present invention.
  • the attitude of the apparatus is as shown in FIG. 1.
  • arm 2 Upon continued rotation of the rigid apparatus carrying structure, arm 2 will contact a stationary cam, not shown, mechanically lowering cylinder I and all of the elements connected thereto, such elements not changing the position thereof relative to the other elements connected to this cylinder, lowering of arm 2 continuing until the lower edge of the housing seat in the lower end of the elongated hollow body 7 contacts the bottom 25 of the valve resting on guide 28 (FIG. 2).
  • tubes 15 and 19 are connected to a pressure air supply, and tubes l4, 16, I7 and I8 are connected to vent.
  • valves are operated so as to first provide for connecting tube 14 to vent and connecting tube 15 to the pressure air supply, thus causing piston 9 to move upward within head 8 and the lower end of tube 11 to move upward relative to the seam folding pliers, which are thus cleared of the bottom previously seam folded to the container (see FIG. 6).
  • first piston d is upwardly moved within cylinder 1 and then piston 3 is also upwardly moved therein, to move back to the position shown in FIG. I, whereupon the processing cycle is restarted as described.
