摘要:
A rotary labelling machine comprises a carrousel that can be pivotally driven by a carrousel motor and a plurality of container stations supported by said carrousel, wherein each container station comprises a container-holder plate and a plate motor suitable to rotate the plate about its own axis, carrousel sensor means detecting the movement of the carrousel and generating a reference signal representative of the carrousel angular position, a plurality of local control units. Each control unit is connected with one of the plate motors, respectively, and is configured to receive and process the reference signal and generate a control signal specific for said plate motor. Signal propagation means are connected to the carrousel sensor means and to the local control units to propagate the reference signal to each of the local control units.

The invention is generally applicable to labeling apparatus, and relates to a device (10) for rotating Container plates in a labeling apparatus; such device (10) being engaged by at least two wheels (1) with a cam (5) for guiding and rotating it, so that the plate connected therewith is also rotated; each wheel (1) consisting of at least one rigid element (2) and at least one elastic disk (3) coupled thereto, having a greater outside diameter, so that the cam (5) is first contacted by said elastic disk (3). As the load between the elastic disk (3) and the cam (5) is increased, and such disk (3) is elastically deformed, the cam (5) is contacted by the rigid element (2).

A pressure adjustment device applicable in particular, but not exclusively, to stretch blow moulding machines. More particularly, the invention relates to a pressure adjustment device for stretch blow moulding machines of containers made of plastic material. The device includes an opening for dispensing a blowing fluid, a hollow body having a first inlet opening for a high pressure fluid and a second inlet opening for a piloting fluid. A shutter is slidably arranged within the hollow body, the shutter being held in a closed position by elastic means, wherein the adjustable opening of the shutter occurs, in contrast with the elastic means, by introducing—through said second inlet opening—the piloting fluid into a piloting chamber arranged between the hollow body the shutter, and wherein the piloting fluid has a controlled and adjustable pressure.

The invention pertains to the field of apparatuses for automatically determining the beginning of a welding process which makes tubular labels of plastic film. The device comprises a welding element, such as a sonotrode (2) for performing an ultrasonic welding, which is mounted to turrets of a labelling machine. The device is formed of two parts, one movable and one stationary fixed to the turret and comprises sliding elements engaged in a respective guide (4) which allow the sonotrode (2) to slide when it is stopped by the opposite resistance of the object to be welded. Meanwhile, since the distance between said stationary and movable elements diminishes, a spring (11) is compressed and a sensor (8) triggers the translation and welding step. The spring (11) move the sonotrode (2) back to the initial position when the device (1) is moved away from the welded label. The process provides that the welding vertical translating step starts when the sonotrode contacts the labels to be welded.

The present invention relates to a pressurization device, in particular of the type used for high hydrostatic pressure. More particularly, the present invention relates to a pressurization device (1) comprising a casing (4) provided with a closure (3) and housing a pressurization chamber (15), the device (1) being provided with pressurization means for putting the pressurization chamber (15) under pressure, characterized in that the pressurization chamber (15) is sealed by means of a plurality of annular seals (19a, 19b, 19c) arranged in series on the lateral surface of the pressurization chamber (15) at predetermined relative distances (D1, D2) which are correlated with the coefficient of compressibility of the liquid filling the pressurization chamber (15).

A motor for a plate of a labelling machine comprises a housing with a connecting portion for connecting the motor to a carousel of the labelling machine, a motor shaft pivotally supported within the housing, a coupling flange having a first end connected to the motor shaft and a second end that can be connected to the plate. The motor shaft and coupling flange are joined as one piece such as to form a one-body shaft-flange unit.

The present invention relates to a hydraulic pressurization system, in particular for application to pressurization devices operating in accordance with the high hydrostatic pressure principle. In particular, the present invention provides a pressurization system for modifying the pressure in a pressurization device. The system comprising a first hydraulic circuit in which one or more primary pressure accumulators are connected to the pressurization device in controlled manner in order to permit a substantially incompressible fluid to be admitted to and removed from the pressurization device at a first pressure, the primary pressure accumulators being precompressed-gas pressure accumulators.
