摘要:
A fluid-agitating tank assembly (1) comprising a tank (10), filled in use with a fluid, in particular a fluid with particles, and agitator means (11), housed in the tank (10) so as to be immersed in use at least partly in the fluid and supported by the tank (10) in a rotatable manner about an axis (D); the agitator means (11) comprise: - a double helix (26) housed in an upper volume (27) of the tank (10) and acting in use on the fluid to transform unidirectional rotation of the agitator means (11) about the axis (D) into a bidirectional movement of the fluid in the tank (10) towards bottom and top portions (13, 14) of the tank (10), and - at least one rotary blade (28, 28') projecting transversally from the axis (D), housed in a bottom volume (29) of the tank (10) and rotating in use about the axis (D) to move the fluid towards at least one lateral outlet (25) of the tank (10); the tank assembly (1) further comprises at least one fixed blade (30) housed in the tank (10) and adapted to at least in part decouple from one another the fluid motions in the top and bottom volumes (27, 29) of the tank (10).
摘要:
The labels used in a labelling machine for containers, in particular bottles, are separated by a roll (2), which is mounted on a central pin (4), and is locked against a support surface (P) by a locking ring (7) provided with a sleeve (8) which is coupled to the central pin (4) in a sliding manner, and with at least two coupling blocks (16) which are mobile, relative to the sleeve (8), between an extracted operating position, wherein the coupling blocks (16) are fastened to the central pin (4), and a retracted rest position, wherein the coupling blocks (16) disengage the central pin (4) itself.
摘要:
There is disclosed a filling unit (1) for contact or contactless filling an article (2) comprising: a tank (6) comprising: a first valve (16), which may allow or prevent the fluidic connection between first region (7) of tank (6) and article (2); a first fluidic line (35) which extends from tank (6) to article (2) in case of contact filling; a second valve (42), which may allow or prevent the flow along first fluidic line (35); and a control unit (45) configured to set first valve (46) in a first closed configuration and second valve (42) in a second open configuration in case of contact filling, so as to pressurize article (2) before the filling with pourable product; filling unit (1) further comprises a second fluidic line (44), which is distinct from first fluidic line (35) and extends from the inner volume of article (2) to a discharge area (55) distinct from tank (6); and a third valve (46), which may allow or prevent the flow along second fluidic line (44); control unit (45) is configured to set first valve (16) in first open configuration and third valve (46) in a third open configuration in case of contact filling, so as to allow an aeriform contained in article (2) to be discharged from article (2) during the contact filling of article (2).

摘要:
There is disclosed a unit for contact or contactless filling an article (2) with a pourable product, comprising: a filling device (10) movable along a path (P); a holding device (17) movable together with filling device (10) along path (P) and adapted to hold article (2) and to move it with respect to filling device along a direction (B) between a first rest position and a second operative position; and a cam (49); holding device (17) comprises: a gripping member (18) for gripping article (2); a cam follower (48) interacting with cam (49) along a first portion (P1) of path (P) and connected to gripping member (18); and an actuator (51) controllable to exert on gripping member (18) an action directed along direction (B) and in a first sense; actuator (51) is selectively arrangeable in a first configuration, in which it exerts action and with a first value along first portion (P1) of path (P), so as to thrust cam follower (48) against cam (49) and to keep article (2) in first rest position; actuator (51) can selectively be set in a second configuration, in which it exerts action with a second value, greater than first value, along one first region (β, γ, ε, ζ) of a second portion (P2) of path (P), so as to move article (2) towards second operative position.
