摘要:
This invention relates to a plate (1) for a labelling machine (10) with a carrousel. The plate (1) comprises a disk-shaped support (3) for a container (9) to be labelled. The disk-shaped support (3) is associable with a bottom (92) of the container (9) and is rotatable about an axis of rotation (30). The plate (1) comprises at least three hooking teeth (41, 42, 43, 44) which are arranged on a teeth-holding member (40) in positions spaced along an arc of a circle that is centred on the axis of rotation (30). Each hooking tooth (41, 42, 43, 44) is insertable in a respective recess (961, 962, 963, 964) made in the bottom (92) of the container (9). The teeth-holding member (40) is movable relative to the disk-shaped support (3) along an axial line, whereby the hooking teeth are movable relative to the disk-shaped support (3) between an engaged position, in which they are inserted in the respective recesses of the container (9) thereby hooking the container (9), and a disengaged position, in which the hooking teeth are not associated with the respective recesses. The disk-shaped support (3) is angularly shiftable relative to the teeth-holding member (20), whereby the container (9) supported by the disk-shaped support (3) is angularly shiftable relative to the hooking teeth (41, 42, 43, 44) for positioning the hooking teeth (41, 42, 43, 44) at the respective recesses (961, 962, 963, 964). The hooking teeth (41, 42, 43, 44) are in positions that are angularly spaced from one another and that overall do not have rotary symmetry relative to the axis of rotation (30). In use, with respective recesses (961, 962, 963, 964) of the container (9) that have corresponding angular distances, the hooking teeth (41, 42, 43, 44) are simultaneously insertable in the recesses (961, 962, 963, 964) for only one mutual angular position of the container (9) relative to the hooking teeth (41, 42, 43, 44). This invention also relates to a labelling machine (10) with a carrousel and a container (9).
摘要:
A device for supporting reels of webs with self-adhesive labels for labelling machines comprising a supporting structure (5) and at least two supports (6) each for supporting a reel of web with self-adhesive labels fixed on one side of it; the supports (6) being rotatably mounted or mountable on the supporting structure (5), one at a first position and one at a second position; the positions of the two supports (6) being invertible, and a support (6) positioned in the second position being movable to the first position, in use, allowing, during the entire movement, unwinding of a web from a reel (14) mounted on it and feeding to a labelling machine.
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.
摘要:
A device for feeding labels to labelling machines comprises means (2) for feeding a web (3) with labels attached to it, a station (4) for detaching the labels from the web (3) and means (5) for recovery of the web (3) without labels attached to it. There are also drive means (10) for the web (3), operating on the web (3) simultaneously upstream and downstream of the detachment station (4) to supply to the detachment station (4) and remove from the detachment station (4) practically the same quantity of web (3) at any time. The device also comprises means (22) for detecting the quantity of web (3) supplied to and removed from the detachment station (4) at any time, and control means operatively connected to the feed means (2), the recovery means (5) and the detector means (22), for regulating the quantity of web (3) fed and recovered at any time, respectively by the feed means (2) and the recovery means (5), according to the instantaneous quantity of web (3) detected by the detector means (22).
