摘要:
There is described a labelling unit (15) movable along a path (P) for receiving an article (3) and a label (2) and for applying said label (2) onto said article (3), the unit (15) comprising support means (20, 38); a movable member (22) adapted to carry the article (3) and supported by the support means (20, 38) in sliding and rotating fashion with respect to an axis (F); and actuator means (35, 36, 41, 50) for producing distinct movements of the movable member (22) in different operative steps of the labelling unit (15); the distinct movements comprising a pure rotation about the axis (F) and a translation along the same axis (F); the actuator means comprising a motor (35); a driving shaft (36) coaxially coupled to the movable member (22) and actuated by said motor (35) to rotate about the axis (F); first transmission means (90) for angularly coupling the motor (35) with the driving shaft (36); wherein the actuator means further comprise second transmission means (41) selectively actuatable to transform the rotational movement imparted by motor (35) to driving shaft (36) in a resulting movement of the relative movable member (22) having an axially translational component; the second transmission means (41) being radially fixed with respect to the support means (38).
摘要:
A filling unit (10) of a filling machine (1) engages at least one container (2) to carry out filling thereof with a filling product, and is provided with an electronic control module (20), integrating a computing unit (22), and a communication interface (28), coupled to a communication bus (32) for communication with a central control unit (30). The computing unit (22) autonomously and independently initiates communication with the central control unit (30) over the communication bus (32), and asynchronously issues one or more interrupts (INT) over the communication bus (32) in order to communicate with the central control unit (30).
摘要:
There is described a vacuum drum (7) adapted to transfer at least one label (2a, 2b) along a given path (P) around a rotation axis (A), comprising: a main body (9) delimited by an outer lateral surface (11) which is adapted to receive label (2a, 2b) to be transferred; and at least one first and one second port (10a, 10b; 10c) defined by surface (11); vacuum drum (7) comprises a selectively mountable first distributor (30, 30') configured for fluidly connecting, on the basis of the format of label (2a, 2b),: first second port (10a, 10b) to a first source (22) of vacuum at a first higher degree of depression, so that a suction action is exerted by first port (10a, 10b) on label (2a, 2b), and/or second port (10c) to a second source of vacuum a second lower degree of depression, so as to selectively prevent second port (10c) from exerting a suction action on label (2a, 2b).
摘要:
A batcher (1) comprising: - a body (11) defining a feeding duct; - a shutter (12) mobile, within the body (li), between relative closed and open positions; and - means (50) for actuating the shutter comprising a first pair of magnets (52, 52' ) external to the body (11) and adjacent to one another with identical magnetic poles facing axially; the shutter (12) comprising a second pair of magnets (127, 127') adjacent to one another with identical magnetic poles facing axially, coupled magnetically with the first pair of magnets (52, 52' ) and arranged, with respect thereto, with different magnetic poles reciprocally facing radially; the shutter (12) comprising a stem (121) and a plurality of fins (122, 122') projecting radially from the stem (121) and adapted to slidingly guide the shutter (121) within the body (11); an annular duct (124) adapted to allow the flow of a pourable product comprising suspended solid particles being defined between the stem (121) and the body (11).
