Benefits of technology

"The present invention provides a machine and method for filling capsules or similar with at least two products. The machine and method aim to eliminate the drawbacks of current methods."

Problems solved by technology

Because the above operating sequence has to be performed twice—once for each product fed into the metering chamber—for each complete turn of the metering wheel about its longitudinal axis, and, each time, the piston has to perform a relatively large number of movements along the metering chamber, some merely to weigh the piston portion projecting inside the metering chamber, known machines of the above type have several drawbacks, mainly due to the relatively high travelling speed of the piston along the metering chamber, which jeopardizes not only correct filling of the metering chamber, but also correct weighing of the piston portion projecting inside the metering chamber, and each product inside the metering chamber.

Embodiment Construction

[0023]With reference to FIGS. 1 and 3, number 1 indicates as a whole a machine for filling known capsules (not shown) with at least one pharmaceutical product in granules. Each capsule (not shown) comprises a substantially cup-shaped bottom shell 2, and a top shell (not shown) closing bottom shell 2.

[0024]Machine 1 comprises a metering wheel 3, in turn comprising a supporting shaft (not shown), which has a substantially vertical longitudinal axis 4, is fitted to a fixed frame 5 of machine 1, is rotated continuously about axis 4 and with respect to frame 5 by a known drive device (not shown), and supports a metering drum 6.

[0025]Drum 6 comprises a bottom disk 7, an intermediate disk 8, and a top disk 9, which are coaxial with and perpendicular to axis 4, and are connected in angularly fixed manner to one another and to the supporting shaft (not shown) to rotate about axis 4.

[0026]On the outer surface of disk 7 are formed: a sprocket 10 coaxial with axis 4 and forming part of a known ...

Abstract

The bottom shell of a capsule is filled with at least two products, contained in respective tanks, by means of a metering device, which has a metering chamber for receiving a given quantity of product from each tank; and a transfer chamber, which receives and transfers the product from the metering chamber to the bottom shell, and has a weighing device for weighing the product inside the transfer chamber.

Description

[0001]The present invention relates to a machine for filling capsules or similar with at least two products.[0002]More specifically, the present invention relates to a machine for filling capsules with pharmaceutical products in granules, to which the following description refers purely by way of example.BACKGROUND OF THE INVENTION[0003]In the pharmaceutical industry, a machine for filling capsules with pharmaceutical products in granules is known comprising a conveying device moving continuously along a given path and having a number of pockets, each for receiving a respective bottom shell of a capsule; two tanks of respective products; and a metering wheel mounted to rotate continuously about a substantially vertical longitudinal axis.[0004]The metering wheel has a number of metering devices, each of which is moved by the metering wheel along a portion of the bottom shell path, in time with, and so as to transfer a given quantity of each product into, a respective bottom shell.[00...
