Embodiment Construction

[0047] refer to Figures 1 to 7 , which shows a filling machine 1 for dosing a product (for example in powder, liquid or granular form) inside a capsule 200 or similar element, especially a hard gelatin capsule.

[0048] The machine 1 is provided with a turret arrangement 2 of known type and not shown in detail in the figures, comprising a single operating turret rotatable about a vertical axis of rotation X1, and the machine 1 comprising a plurality of operating stations 21 , each operating station is suitable for processing, ie performing a series of operations on, empty capsules 200 drawn from the first storage 3 , also supported by said turret 2 .

[0049] In the operating station 21 , all steps of processing the capsules 200 are performed sequentially during the rotation of the turret 2 with the continuous movement. Empty capsules 200 from the first store 3 reach the operating station 21 via a corresponding supply duct 22 . In the operating station 21 , the capsules 200...

Abstract

A machine for dosing a product in capsules (200, 201), or similar elements, comprises the steps of rotating turret means (2; 102) which have seats (24; 124) suitable for receiving capsules (200) drawn empty from a first store (3; 103) and dosing means for dosing the product in the capsules (200), the machine further comprising: a feeding unit (4) having first weighing means (5), for weighing further capsules (201) drawn empty from a second store (6); transfer means (7; 107) for transferring the further capsules (201), when weighed, to predetermined seats (24; 124) of the turret means (2; 102) for being filled with the product; second weighing means (45) for weighing the further capsules (201) filled with the product and taken out from the turret means (2; 102); and processing means (50) connected to the first weighing means (5) and to the second weighing means (45) for receiving data relative to weights measured by means of the first and second weighing means (5, 45) and for calculating for each further capsule (201) a difference between a weight measured before and a weight measured after filling, in such manner as to calculate a respective quantity of dosed product.

Description

technical field [0001] The present invention relates to a machine and method for filling capsules or similar elements with medicinal products, and in particular to a filling machine of the single turret type comprising weighing means suitable for determining the net weight of the capsules, ie the weight of the dosed product. Background technique [0002] During the filling of hard gelatin capsules with medicinal products, eg liquid, powdered, granular or tableted, it is known to use a weighing device or device arranged downstream of the filling machine to measure the weight of the dosage product inside the capsule. [0003] The weight has to be checked to reject product capsules which are not allowed because the amount of product they contain is outside the permitted dose tolerance range and to correct possible excesses or shortages in dosing the product by acting in feedback on the filling unit of the machine. [0004] Especially in the pharmaceutical field, it is important...
