Method and machine for filling capsules or similar with at least two products, in particular pharmaceutical products in granules

Abstract

The invention discloses a machine and a machine for filling capsules or similar with at least two products, in particular pharmaceutical products in granules. Each capsule includes a bottom case and a top case for closing the bottom case. The machine includes a forwarder, at least two of reservoir, at least one of dosing wheel, and a plurality of metering devices. Each of the metering devices is supplied by the dosing wheel along a part of a path (P) to the corresponded bottom case, so as to provide products to the bottom case. The metering devices include a measuring cavity. The characteristics of the machine are described as that: each metering device also includes a conveying cavity used for receiving and transforming products came from the corresponding measuring cavity, and includes a weighing device used for weighing the products came from the conveying cavity. The invention also discloses a method for filling capsules or similar with at least two products, in particular pharmaceutical products in granules.

Description

technical field [0001] The invention relates to a machine for filling capsules or the like with at least two products. [0002] More specifically, the invention relates to a machine for filling capsules with granular pharmaceutical products, which is described below by way of example only. Background technique [0003] A machine for filling capsules with granular pharmaceutical products is known in the pharmaceutical industry, comprising a conveyor, two reservoirs of the corresponding product and a metering wheel; the conveyor moves continuously along a given path and has a plurality of pockets, a plurality of Each of the pockets is intended to accommodate a respective bottom shell of a capsule; the metering wheel is mounted for continuous rotation about a substantially vertical longitudinal axis. [0004] The metering wheel has a plurality of metering devices, each metering device being moved by the metering wheel along a portion of the path of the pan in time with the res...

AI Technical Summary

Problems solved by technology

[0014] Since for each complete cycle of the metering wheel around its longitudinal axis, the above sequence of operations has to be carried out twice (once for each product fed into the interior of the metering chamber), the piston has to perform a relatively large number of steps along the metering chamber each time. movement, some only need to measure the weight of the part of the piston protruding into the inside of the metering chamber, known machines of the above type have several drawbacks, mainly due to the relatively high speed of the piston along the metering chamber, which is not only critical for the correct filling of the metering chamber adversely affect the correct weighing of the portion of the piston protruding into the metering chamber and of each product inside the metering chamber
