On a machine for producing articles, in particular a packaging machine for producing packets of cigarettes, a reel, laid flat on a support, is fed, by means of a transfer device, to a relative unwinding pin fitted to the periphery of a rotary platform rotating about a substantially horizontal axis; the unwinding pin being set to a substantially radial position with respect to the platform axis; the rotary platform being rotated to set said unwinding pin to a vertical receiving position facing upwards; the reel being fitted downwards onto the unwinding pin in the receiving position; and the unwinding pin being rotated, with respect to the rotary platform, into an axial position with respect to the rotary platform before unwinding the reel.
摘要:
A method and device for forming groups of products, whereby a substantially continuous input succession of products is fed to an input of an endless conveyor, which has a conveying branch and a return branch extending between the input and an output, and which has a variable speed drive member operated to impart a variable speed to the conveyor at the input, and to generate, along the conveying branch, a succession of equally spaced on-line gaps defining a succession of groups of products; the conveying and return branches are both engaged by a powered compensating device for varying the lengths of the conveying and return branches in complementary manner, so as to maintain a constant speed of the conveyor at the output and compensate for any gaps in the input succession.

A transfer unit for transferring blanks and supplying a feed store of a packing machine has two transfer devices, and a first and a second store in which the blanks are arranged in stacks; and the transfer unit supplies the feed store by transferring the stacks of blanks selectively from the first store to the feed store, and from the second store to the feed store.
摘要:
A method and unit for transferring blanks on a packing machine, whereby stacks of blanks are transferred from a platform, on which the blanks are arranged in stacks, to a store wherein the blanks are packed successively and seamlessly along a path for supply to a pickup station of the packing machine; transfer of the stacks from the platform to the store including forming, at a loading station and by means of two gripping devices for gripping the stacks, a group of blanks defined by stacks superimposed and aligned in a container, feeding the container and the group along a path to an unloading station at the store, and transferring the group of blanks from the container to the store.
摘要:
A method and unit for applying labels to packets of cigarettes, traveling in a given direction along a first path with a given spacing and arranged a given distance apart, provide for feeding a gripping head along a second path, and applying each label to a first face of a respective packet by inserting the gripping head between one packet and the adjacent following packet to roll the gripping head and apply the label along the first face, which is perpendicular to the given direction.
摘要:
A method of conveying articles provides for feeding an article to a pocket travelling along a conveying path; gripping the article by means of suction holes located along a plate of the pocket; feeding the article and the pocket along the path; releasing and pushing the article against a locating member of the pocket as the article and the pocket are advanced; and gripping the article to the plate by means of the suction holes.
摘要:
A pickup device for stacks of blanks arranged in at least one layer on a substantially horizontal separating sheet, wherein a fork, movable in a given pickup direction to and from the separating sheet to successively pick up the stacks by sliding in contact with the separating sheet, has a skid hinged to a free end of the fork; the skid sliding in contact with the separating sheet, and oscillating, with respect to the fork, about a substantially horizontal axis crosswise to the pickup direction.
摘要:
A method and machine for on-line treating and/or processing containers (2), whereby a container (2) is fed along a production line (45), a portion of which is defined by an endless conveyor (3) extending through a loading station (43; 55) and an unloading station (41; 55) for containers (2); the container (2), as it is fed along by the conveyor (3), being subjected to a treatment and/or processing operation inside a respective cell (17), which is movable with the conveyor (3) to receive the container (2) at the loading station (43; 55) and to release the container (2) at the unloading station (41; 55).
摘要:
A method of feeding cigars to a hopper of a wrapping machine, wherein the cigars are housed in bulk and in orderly manner inside containers; each container has a top opening by which to receive and unload the cigars in the aforementioned orderly manner; a full container of cigars is picked up and inverted at the hopper by means of a manipulating device so that the opening faces downwards; and the full container is rested on a supporting surface having a passage smaller than the opening, so as to partly close the opening and provide for controlled unloading of the cigars.
