DESCRIPTION:
BRIEF SUMMARY
The present invention concerns vacuum packaging of containers which are intended in particular to receive powder or granular materials.
The advantages which are achieved by filling sealed rot-proof containers under vacuum for the storage and handling of materials in powder or granular form are known.
A first advantage of packaging under vacuum is to permit all materials to be stored outside, with bad weather having no effect on the state of the materials which are packaged in that way.
A second advantage is the ease of handling of the containers to which the pressure of the air imparts a degree of rigidity which is largely sufficient to permit them to withstand the shocks and impacts which are inherent in handling operations carried out without particular precautions being taken.
A third advantage is good conservation of foodstuff and articles considered to be perishable, the vacuum preventing any oxidation, chemical reaction, hatching of insect eggs, mould and mildew or other disadvantages which are conventionally involved in the storage of perishable articles.
The recognised advantages of vacuum packaging of materials in powder or granular form are in practice of an economic significance such as to justify the use of expensive packaging equipment, in particular when containers of substantial dimensions are involved.
Those known apparatuses are conventionally formed by means for pouring the materials into the containers and means for sealing the containers, which are disposed in a vacuum chamber.
The corresponding processes involve opening the vacuum chamber, closing it, carrying out the different operations including producing the vacuum in the chamber, restoring the air therein and opening the chamber, and finally extraction of the containers.
That involves a number of disadvantages:
A vacuum chamber must contain the whole of the means for filling and sealing the containers.
The feed of materials to the filling means within the chamber is a complicated aspect and requires the use of expensive equipment.
A single container can be filled and packaged simultaneously in a vacuum chamber.
In order to package a plurality of containers simultaneously, it is necessary to use an equal number of vacuum chambers, implying installations involving a substantial level of cost.
An object of the present invention is an apparatus for permitting the simultaneous packaging of a plurality of containers, while retaining simplicity in the means used, which considerably reduces its cost in comparison with the prior-art apparatuses.
Another object of the invention is a process for vacuum filling containers using an apparatus according to the invention.
More precisely, an apparatus for filling containers under vacuum with materials in powder or granular form, according to the invention, comprising in combination: which rotates discretely and intermittently through an angle of 360.degree./N, N being a number of support means suitable for each receiving a container, N being at least equal to three, said support means being fixed with respect to the turntable and distributed at the periphery thereof at an angular spacing of 360.degree./N, and that said fixed means are distributed at two fixed stations disposed at an angular spacing of 360.degree./N from each other.
In addition, the discrete rotary movement through 360.degree./N of the turntable takes place at regular intervals of time, while interposed stoppage periods may also be regular.
In accordance with another aspect of the invention the two fixed stations are respectively disposed in vertical alignment with two of the support means for each stopped position of the turntable.
More precisely the material conveyor means, the material weighing means, and the means for pouring the materials into the containers are combined at a first fixed station in vertical alignment with a stop position of a support means, and the means for putting containers under vacuum and the means for sealing containers are combined at a second fixed station disposed in vertical alignment with a support
