摘要:
A unit for the glue application of at least two labels to containers, comprising at least one first application device (8) and one second application device (9) both of which rotate and are positioned at two separate superposed portions of the main axis of rotation (Z), each for applying at least one label on a separate portion of the same container (2). In practice, the operating parts of the two application devices (8) and (9) are at different distances from the axis of rotation (Z), although they rotate at identical rotational speeds relative to said axis. The second application device (9) comprises two first follower elements (30) which are slidably connected to a stationary first guide element (29), for guiding the movement of the second device in space. At least at the label application position (24), the interaction between the first follower elements (30) and the first guide element (29) causes an oscillation of the second application device (9) for varying the speed of movement of its operating part and adapting it to that of the container to be labelled.

A device (1) for feeding self-adhesive or "pressure sensitive" labels to a labelling machine comprises a frame (2) and supporting means (3) comprising a supporting plate (17) for supporting a reel (4) of web (5) with labels applied to it, and also comprises at least one guide element (28, 29) designed to be at least partly inserted in a central hole (7) of the reel (4) which can rotate about it. The device (1) also comprises a detaching station (8) for detaching the labels from the web (5), feeding means (9) for feeding the web (5) to the detaching station (8) and recovery means (10) for recovering the web (5) without labels. The supporting plate (17) is removably associated with the frame (2) and the supporting means (3) also comprise a containment head (30) switchable between an open configuration, in which it allows the coupling with and uncoupling from the frame (2) of the supporting plate (17), with the reel (4) placed on it, and an operating configuration, in which it allows the reel (4) to be held between itself and the supporting plate (17), allowing reel (4) rotation.
摘要:
This disclosure relates to a labelling machine (1), comprising a carousel (3) rotatably mounted a supporting frame (2) in such a way that it can rotate about a first axis of rotation (30) and a plurality of supporting elements (4) for articles to be labelled (9). The supporting elements (4) are mounted on the periphery of the carousel (3) and are able to rotate about respective second axes of rotation (40). The machine (1) is characterised in that it comprises an operating unit (55) which is mounted on a rotary support (6) mounted on the supporting frame (2). The support (6) is able to rotate about a third axis of rotation (60) which is at a distance, along a radial line, from the first axis of rotation (30). The carousel (3) is movable relative to the third axis of rotation (60) and the operating unit (55), which is rotatable together with the rotary support (6), is designed to perform an operation on a lateral surface of an article (9) which is on its operating line when the article (9), positioned on a respective supporting element (4), passes near to the operating unit (55) during the rotation of the carousel (3). The rotation of the rotary support (6) about the third axis of rotation (60) is coordinated with the rotation of the carousel (3) about the first axis of rotation (30), whereby, in use, the rotation of the rotary support (6) about the third axis of rotation (60) keeps the operating unit (55) with the operating line towards the article to be labelled (9) along a stretch of angular movement of the carousel (3) about the first axis of rotation (30).
摘要:
A labelling machine with a carrousel comprises a carrousel (3) and a plurality of plates (4), mounted on the carrousel (3). Each plate (4) comprises supporting means (13) and a dragging element (14), comprising a tooth (15) substantially insertable in a recess made in the bottom of the container supported by the supporting means (13). The tooth (15) is off-centre relative to the first axis of rotation and movable relative to the supporting means (13) between an engaged position, in which the tooth (15) is substantially inserted in the recess, and a disengaged position, in which the tooth (15) is not associated with the recess. The machine (1) comprises for each plate (4) coupling means (41), operatively associated with the tooth (15), for coupling the supporting means (13) to the carrousel (3) when the tooth (15) is in the disengaged position, obstructing rotation of the supporting means (13) relative to the carrousel (3), and for uncoupling the supporting means (13) from the carrousel (3) when the tooth (15) is in the engaged position, allowing substantially free rotation of the supporting means (13) relative to the carrousel (3).
摘要:
A device for joining webs with self-adhesive labels comprises a web retaining element (18) for, in use, selectively retaining the starting end (16) of a new web (13) at an operating zone (15) positioned along a feed path of a first web being used and a pressure element (26) positioned on the opposite side of the first web; at least one of either the retaining element (18) or the pressure element (26) being movable relative to the other, between a non-operating position in which they are at a distance from each other and an operating position in which the pressure element (26) presses the first web (10) onto an adhesive element fixed to the new web (13); it also comprises a cutting (27) movable between a non-interference position and a cutting position, movement means for moving the cutting element (27) from the non-interference position to the cutting position, and controlled feeding means for the first web (10) which are operatively associated with the movement means for causing controlled feeding of the first web (10) in the operating zone (15) during movement of the cutting element (27) towards the cutting position. A method for joining implemented by the device is also claimed.

A device (1) for feeding self-adhesive or "pressure sensitive" labels to a labelling machine comprises a frame (2), supporting means (3) for a reel of a web with the labels attached to it, a station (5) for detaching the labels from the web, recovery means (6), return means (8), and means (10) for moving the web comprising: a motor-driven roller (11) and at least one unit (15) for pressing the web against the motor-driven roller (11) comprising at least one contact roller (16), mounted on a support (17), for clamping the web against the motor-driven roller (11). The support (17) being movable relative to the frame (2) between an operating position, with the contact roller (16) pressed against the motor-driven roller (11), and an insertion position, with the contact roller (16) distanced from the motor-driven roller (11). There being a switching element (18) associated with the support (17) which in their first configuration is in the operating position, in a second configuration is in an insertion position and in a third configuration is able to move between the insertion position and a maintenance position in which the contact roller (16) is further from the motor-driven roller (11) than in the insertion position.
