Operating device preferably for machines for controlling and inspecting containers and/or their contents, and corresponding machine

Abstract

The invention is an operating device (1, 100, 200) comprising means (2) suited to move a support (3) with an alternating motion (A) around an axis (4). The means (2) comprise one or more permanent magnets (5) arranged along a section of a circumference that is concentric with the axis (4) and a winding (6) controlled by a control unit (7). The invention also concerns a machine for checking and inspecting containers.

Description

technical field [0001] The invention relates to an operating device and a corresponding inspection machine, which are preferably used in a machine for controlling and inspecting containers. More specifically, the invention relates to a synchronization device and corresponding machines for use in machines for controlling and inspecting containers and / or their contents, preferably in the pharmaceutical sector. Background technique [0002] As is known, certain products are packaged and sealed in containers. [0003] Especially in the pharmaceutical sector, certain products are placed into containers such as bottles or vials made of glass or synthetic material like eg plastic or similar materials and sealed therein. The containers, once sealed and dispatched from the filling and sealing system, are subjected to various inspections and inspections. [0004] The inspection may, for example, identify any foreign particles inside the container and / or its contents and / or defects i...

AI Technical Summary

Problems solved by technology

[0018] A first disadvantage arising from the known types of mechanically synchronized devices used in systems for testing pharmaceutical products is in particular that said devices are complex, heavy and bulky

[0019] Another disadvantage is that the dynamic motion present in the above devices induces mechanical slack and it is therefore difficult to control the movement of the sensor accurately and in a repeatable manner

[0020] A further disadvantage is that the mechanical parts of said mechanically synchronized devices generate friction and are thus subject to wear, which significantly reduces the working life of the mechanical parts themselves and thus of the device containing them

[0021] Yet another disadvantage is represented by the fact that mechanical synchronizing devices require lubrication

[0022] Another disadvantage consists of the fact that the aforementioned friction produces an almost negligible loss of power

[0023] A further disadvantage is that the speeds and accelerations that can be achieved by the sensor are limited

[0024] Another disadvantage is that the elasticity of the parts of the mechanical synchronous device causes mechanical resonance phenomena and thus undesired oscillations and vibrations of the sensor even during the recording phase

[0025] A further disadvantage is represented by the fact that the ratio between the time taken to inspect the container and the time required to run one revolution of the cylindrical support is constant, this ratio is determined by the synchronization of the movement transmitted to the sensor The transmission ratio between the mechanical parts of the kinematic chain of the device is determined by the

[0026] Another disadvantage is that the components of mechanical synchronizing devices must be constructed with high precision and the smallest tolerance values ​​in order to ensure the best possible synchronization between the movements of the carriage and the turning pin

[0027] A further disadvantage associated with the aforementioned one is represented by the fact that mechanical synchronization devices are expensive
