Abstract
The machine includes an endless conveyor having receptacles for holding the vials and the conveyor can be indexed through a multiple number of pitches of the receptacles. Needles and syringes are provided for filling the vials held on the conveyor and, downstream of the needles, there are provided burners and pinch devices which serve to seal the filled vials while they are being rotated by pairs of friction wheels.
Claims8
A machine for filling and sealing glass vials comprising, in combination, a frame having an upper support surface;
- endless conveyor means operable to receive the vials and to move the vials along said support surface;
- said endless conveyor means comprising an endless gear belt having secured thereto, in adjacent relation, a plurality of receptacles adapted to have the vials inserted thereinto from above for resting on said support surface, said receptacles maintaining the vials in an upright orientation during travel of the vials along said support surface;
- indexing means operatively connected to said conveyor means and operable to step said endless belt and said receptacles, cyclically and repetitively, so a distance equal to the length of said endless belt spanned by a plurality of said vials;
- feeding means positioned at a feeding station adjacent said conveyor means and operable, cyclically and repetitively, to feed, into said receptacles, a plurality of vials simultaneously, the plurality of vials being equal to the number of vials in said length span;
- filling means positioned adjacent said conveyor means downstream of said feeding means in the direction of movement of said endless belt, for filling the vials with a liquid;
- said filling means comprising a plurality of syringes equal in number to said plurality of vials fed simultaneously by said feeding means and a plurality of needles, equal in number to said plurality of syringes, each communicating with a respective syringe;
- sealing means positioned adjacent said conveyor means downstream from said filling means in the direction of movement of said endless belt;
- said sealing means comprising a plurality of burners equal in number to the number of vials fed simultaneously to said receptacles by said feeding means, and a plurality of pinch means, equal in number to the number of said burners;
- said burners and the respective associated pinch means being disposed at contiguous sealing stations along the length of said conveyor means whereby the plurality of vials can be sealed simultaneously;
- rotating means at said sealing means operable, during the sealing operation, to engage and rotate the plurality of vials being simultanously sealed;
- discharge means positioned adjacent said conveyor means downstream of said sealing means in the direction of movement of said endless belt and operable to remove, from said conveyor means, the filled and sealed vials;
- and drive means mounted in said frame and including respective control cams for said indexing, feeding, filling, sealing, rotating and discharge means.
