Apparatus with facing bell members, for modified atmosphere packaging of products placed in trays
Methods and apparatus for introducing a modified atmosphere into a package and sealing that package with a film are disclosed. Cooperating upper and lower bell members having internal volumes in fluid communication with one another via a duct configured to cause sequential pressure differentials between the volumes permit the sealing film to be controllably retracted from and applied to outflow holes so as to allow evacuation of ambient air using a single constant vacuum source, rather than requiring precision timing controls and/or multiple vacuum sources. Another dedicate circuit introduces the modified atmosphere into the package, and a sealing unit such as a heat welder subsequently seals the film against the package.

APPARATUS WITH OPPOSING HOUSINGS FOR MODIFIED ATMOSPHERE PACKAGING OF PRODUCTS PLACED IN TRAYS
When the opposing housings (1, 8) of the apparatus are closed, they form between them a small main chamber (P) delimited above by the film (H) for covering the tray and below by the tray (V) itself containing the product (M), and laterally by any suitable mechanical interface structure which surrounds the perimeter of said film and connects it to the perimeter of the upper edge (B) of the tray, this interface structure having holes (22) which are suitably distributed, are located outside the perimeter of the tray, and communicate with said main chamber (P). One or more of these holes (22) open(s) on at least one side of the tray and is/are connected to a first circuit (23, 24), while another one or more of said holes (22') open(s) on at least one opposing side of the tray and is/are connected to a second circuit (17) which in turn is connected to the inner chambers of the two housings (1, 8). Means (18, 19, 20) are provided to operate in such a way that, in the step of vacuum formation, both said first circuit (24) and said second circuit (17) are connected to vacuum forming means (21) which are kept active for a sufficient time to eliminate some of the air from the inside of the tray and to act in such a way that said first circuit (24) is connected in the next step or at the correct time to means (25) for supplying the process gases, while said second circuit (17) is closed or remains in communication with the vacuum means (21) to ensure that the process gas entering the tray from said first circuit (22, 24) causes the residual air in the tray to flow out from and/or towards said second circuit (22', 17), thus flushing and saturating the inner volume of the tray, which is subsequently sealed using known steps and means for welding and finally cutting the film (H).

APPARATUS FOR MODIFIED ATMOSPHERE PACKAGING OF PRODUCTS PLACED IN TRAYS
Between the two housings (1, 18), and below and parallel to the film (F), there is provided a frame (7) having openings (8) with shapes and dimensions suitably greater than the shapes and dimensions in plan view of the underlying trays (V) to be packaged, supported by any means such that, during the closure of the housings (1, 18), this frame (7) interacts with sealing means and contributes to the formation of a main chamber (29) delimited by the upper edge of the tray and by the film above this edge, which is initially connected to the inner chambers (19, 2, 102) of the two housings (1, 18), to enable the air to be removed from these chambers and to form the desired level of vacuum therein, while, in the next step, said main chamber (29) is isolated from the inner chambers of the two housings, so that the process gases for preserving the product can be injected directly into this main chamber, while a corresponding quantity of atmospheric air is directed into said inner chambers of the housings (1, 18) to counterbalance the pressures on the opposite faces of the film which, when the process gases have been fed in, is welded to the edge of the tray and is cut outside this edge by means associated with the upper housing, the whole arrangement being such that, at the end of the cycle, when the housings (1, 18) are opened, no large quantities of process gases are dispersed into the atmosphere, as would be the case in the prior art.

MACHINE FOR THE AUTOMATIC PACKAGING OF LOOSE PRODUCTS OR PRODUCTS PLACED IN TRAYS, WITH A USUALLY HEAT-WELDABLE STRETCH FILM
A machine for the automatic packaging of loose products or products placed in trays, with a usually heat-weldable stretch film, comprises means for unrolling sections of stretch film from a supply reel, separating said sections of film (F) into lengths appropriate for the dimensions of the product to be packaged, by transverse cutting, and positioning the sheet of film thus obtained, horizontally, in a packaging station (C), holding said sheet by the opposite longitudinal sides by means of parallel pairs (G1, G2) of superposed, synchronized belts (1, 3). One, for example the upper, of the parallel sections of the film-positioning and -conveyor belts runs on a fixed support surface (12, 13) while the other, lower one, runs on the jaws (112, 14) of clamps (P1- P5) connected to lifting or lowering means, for pushing the lower belt (1) against the upper belt (3) when required, so as to grasp the film and hold it as necessary both while it is carried along and while the film is being folded under the tray containing the product The invention provides that said clamps (P1-P5) comprise elastic means (16) and are actuated by means of cams (21) fitted on a shaft (22) moved by rotation means (23, 24), said cams being shaped and mutually offset as appropriate, so that said clamps (P1-P5) are actuated differentially and progressively to best meet the requirements of the product packaging cycle.

MACHINE FOR PACKAGING PRODUCTS IN RIGID OR SEMIRIGID TRAYS SEALED ACROSS THE TOP BY A THERMOPLASTIC FILM, PARTICULARLY FOR PRODUCING PACKS IN A MODIFIED ATMOSPHERE
The invention relates to a machine with a series of three operating stations (S1, S2, S3), of which the first station (S1) arranges the full trays in a predetermined pattern in one or two parallel rows, while the intermediate station (S2) closes the full trays with a cover of film heat-sealed onto their top edge, optionally after conditioning the atmosphere inside said trays, to preserve the products packed inside them and also performs the operation of cutting off the sealed trays from the continuous web from which said closing cover is taken, and in which the final station (S3) discharges the full trays, closed and separated, as they come from said intermediate station. Said stations are equidistant from each other in the horizontal direction and said transfer means are composed of moving and lifting combs (16, 16') that operate alongside said stations, that have a length such as to occupy simultaneously two consecutive such stations and that are provided with any means such that the teeth of the combs can be inserted under the front, rear and free space of the groups of the row or rows of trays, without substantially interfering with them, then be raised so as to lift said groups of trays and remove them from the surface they were resting on, then move longitudinally to transfer the groups of trays from one station (S1, S2) to the station immediately following (S2, S3), then be lowered to deposit the groups of trays in the new stations and no longer interfere with the trays, then be withdrawn from said groups of trays, and finally be returned, by a longitudinal movement the reverse of the previous movement, to the start-of-cycle condition.
