Problems solved by technology

[0007] But said weighing device not only has structurally due to the complexity of its components, but also has the above-mentioned obvious disadvantages due to its efficiency in calculating the capsule weight
[0008] In practice, it is not possible to detect defective capsules using the weighing equipment described above, whether the errors in the capsules are due to the uneven weight of the hard rubber cover and / or the body that defines each capsule or due to incorrect dosage of the drug inside the capsules or both caused by
[0009] On the other hand, the device is also not able to detect whether the weight of the cap and / or body of the defined capsule compensates for the underdosing of the drug more heavily in relation to the cap and / or body constituting the other capsules in a qualified detected capsule
[0010] In essence, accurate information about the correctness of the dosage of the capsules containing the drug cannot be obtained using the weighing equipment described above

Embodiment Construction

[0016] The plant 1 comprises a weighing device 2 adapted to detect and check the effective weight of each "empty closed capsule", where "empty closed capsule" refers to the hard plastic cap on which the associated also hard plastic Assemblies formed on the body.

[0017] The device 2 is preferably but not exclusively of the type disclosed and protected in European patent EP 886 765 B1 by the same applicant (the reader is referred to its disclosure and drawings, but not necessarily in detail), which essentially comprises a belt A tumbler with suction seats that picks up empty capsules from a hopper and then delivers them to a set of weighing stations, each of which is arranged in series and on which the capsules to be weighed are positioned Sensors, preferably load cell scales.

[0018] As already shown in this figure, the method of operation of the invention transmits the value of the weight of each empty closed capsule detected by the relevant scale of the device 2 to the ce...

Abstract

A method for checking capsules comprises in sequence the phases of weighing each empty capsule and associating the related empty weight value with said capsule by applying a related identification code to the capsule; filling the capsules with doses of filling material, preferably pharmaceutical material; weighing each capsule filled with said material to obtain a related weight value of the filled closed capsule and interpreting the identification code carried by said capsule and relating to its empty weight value; and comparing the weight value of the filled capsule with the empty weight value carried by the aforementioned code in order to detect and check the correctness of the dosage of the material inside each capsule.

Description

technical field [0001] The present invention relates to a method of inspecting capsules. [0002] The invention is especially useful for the manufacture of cap-body hard gelatin capsules with weight control and especially for checking their quality in powder or solid form, such as tablets, microtablets, delayed-action tablets, or in liquid form. Dosages, these forms will be explicitly referred to in the description below without loss of general relevance. Background technique [0003] Manufacture of cap-body hard gelatin capsules filled with drug by using an automatic capsule filling machine with a turntable, which operates in a sequence of main operating phases which successively consists of: for each closed capsule on a separating station an opening phase that separates the caps and corresponding bodies so as to form two related sequences of caps that are separated from each other, followed by administering the appropriate amount or dose of drug to each body on the dispen...
