ABSTRACT:
The present invention relates to a machine for filling capsules with at least one product.
More specifically, the present invention relates to a machine for filling capsules—each comprising a bottom shell and a top shell fitted to the bottom shell—with at least one powdered pharmaceutical product, to which the following description refers purely by way of example.
BACKGROUND OF THE INVENTION
In the pharmaceutical industry, a capsule filling machine is employed comprising a conveyor which moves continuously along a given path and has a number of pockets equally spaced along the path, and each for receiving a respective bottom shell.
The machine also comprises a metering wheel mounted to rotate continuously about a central axis of symmetry, and having a number of metering devices, which are equally spaced about said axis with the same spacing as the pockets, move with the metering wheel along a portion of said path, each in time with a relative pocket, and move with respect to the metering wheel in a direction parallel to the metering wheel axis.
The machine also comprises an annular container housing the powdered pharmaceutical product, and which is mounted to rotate continuously about a further central axis of symmetry parallel to and eccentric with respect to the metering wheel axis, so that each metering device is first positioned facing the container to withdraw a given quantity of pharmaceutical product from the container, and is then positioned facing and coaxial with a relative bottom shell, into which it feeds the withdrawn pharmaceutical product.
Since the container is supplied by a hopper extending radially outwards from the outer periphery of the container, known machines of the above type are relatively bulky.
BRIEF SUMMARY OF THE INVENTION
It is an object of the present invention to provide a machine for filling capsules with at least one pharmaceutical product, designed to eliminate the aforementioned drawback.
According to the present invention, there is provided a machine for filling capsules with at least one product, each capsule comprising a bottom shell and a top shell; the machine comprising a conveyor moving continuously along a given path and having a number of pockets, each for receiving a respective bottom shell; at least one metering wheel rotating continuously about a first axis, and having a number of metering devices moving with the metering wheel along a portion of said path, each in time with a relative said pocket, to feed a given quantity of said product into a relative said bottom shell; a container housing said product and moving about a second axis substantially parallel to said first axis, each said metering device withdrawing the relative said quantity of product from said container; and supply means for feeding said product into said container; and being characterized in that said supply means comprise at least one supply conduit extending downwards inside a space enclosing said metering wheel and said container.
