摘要:
Containers (2) for food products are manufactured on a machine (1) equipped with a feed station (4) supplying a single file of tubular elements (2a), a first heat sealer (10) by which a first open end (2b) of each tubular element (2a) is closed and secured, and a first rotary conveyor (3) capable of movement between a first operating position in which the tubular elements (2a) are taken up from the feed station (4), and a second operating position in which the tubular elements (2a) are offered to the first heat sealer (10). The same machine (1) is equipped with a second heat sealer (36) such as will complete the container (2) by closing and securing a second open end (2c) of each tubular element (2a) opposite to the first open end (2b), and incorporates a second rotary conveyor (32) located between the first conveyor (3) and the second heat sealer (36), capable of movement between a first operating position in which the partly enclosed tubular elements (2a) are taken up from the first conveyor (3), and a second operating position in which the tubular elements (2a) are offered to the second heat sealer (36).
摘要:
A system (1) for manufacturing containers (5) is designed around a supporting structure (2) with which all the stations (7, 18, 19, 21, 24, 25) and the devices (14, 15, 16, 17, 20, 22, 26) needed to produce the containers are associated. The system (1) is equipped with a feed station (7) supplying a forming material (9), a scoring station (18) by which crease lines (4a) are generated, and a cutting station (19), combining to prepare a succession of blanks (4). The system (1) also includes a prefolding station (21) where each blank (4) is bent initially along the creases lines (4a), a folding station (24) where the single blank (4) is fashioned to the shape of the container (5), and a sealing or welding station (26) at which the shape of the container (5) is fixed definitively.
摘要:
Containers (2) for food products are manufactured employing a system that includes a feed station (4) supplying a succession of tubular elements (2a), and a heat sealer (10) positioned to close and secure a first open end (2b) of each tubular element (2a) that coincides with the base of the container. The sealing operation occurs at a station associated with a conveyor (3) consisting in a wheel (11) rotatable in a feed direction (B) along a path (P) passing both through the feed station (4) and through the station occupied by the heat sealer (10). The tubular elements (2a) are carried by radial elements (13) of the wheel (11) such as can be indexed between a first operating position, where the tubular elements (2a) are taken up from the feed station (4), and a second operating position in which the open end (2b) is offered to the heat sealer (10).
摘要:
A device for the pneumatic inspection of cigarettes comprises a roller which turns about an axis of rotation and has a plurality of seats, each designed to receive a cigarette. For each seat the device has a pair of caps made of strong material, designed to connect with the ends of the cigarette in such a way that, at an inspection station, each cigarette is connected to a source of a fluid which can subject the cigarette to the action of the fluid. A pneumatic—electric pressure transducer is connected to each seat. The transducer issues a signal which depends on the action of the fluid and which indicates the state of the cigarette.
摘要:
A unit and method for transferring cigarette portions whereby the cigarette portions are transferred from a manufacturing machine to a filter assembly machine by means of a first conveyor having first seats movable along a first annular path to pick up respective cigarette portions at a pickup point, and by means of a second conveyor having second seats movable along a respective second annular path; the cigarette portions are transferred from a first seat to a second seat at a transfer point along the first path, and the speed of the second seats is corrected at the transfer point to substantially reach or approximate the speed of the first seats at the transfer point.
摘要:
In equipment utilized for conveying rod-like articles such as cigarettes, which typically are held for a given duration while in transit inside at least one enclosure, a favorable atmosphere is maintained within the enclosure by means of an air conditioning unit interlocked to an array of sensors, located in and monitoring significant parameters internally of the enclosure itself, and governed by a control unit operating in conjunction with the sensors.
摘要:
A method and device whereby a first runout strip, fed at a first speed along a guide by a traction device, is replaced with a new strip by cutting the first strip; activating both a push device, by which the new strip is engaged and fed along the guide at a second speed, and a movable guide device a portion of the guide and which is lowered in relation to the rest of the guide and together with a trailing portion of the first strip on the movable guide device itself; and controlling the second speed as a function of the first speed so that a leading portion of the new strip is superimposed on the trailing portion of the first strip along the movable guide device.
