The present invention relates to a machine for the automated packaging of fruit or vegetable products.
In particular, the invention finds advantageous exploitation in the automated filling of containers, such as trays, cases, boxes or equivalents, with cherries or similar small fruits, to which the following description will make explicit reference without thereby losing generality.
The main object of the invention is the achievement, without any intervention of the staff, of the accurate and delicate filling of products inside the containers.
Another object of the present invention is to realize an effective, precise, constant and optimal control of the weight of containers during all the filling steps.
The structural and natural characteristics of the present invention and its advantages referring to the known technique will be even clearer and evident by the underlying claims, and in particular by an exam of the following description, referring to the annexed drawings, which show the outlines of a preferred but not limitative embodiment of a filling machine, in which:
With reference to the accompanying
Machine M comprises a frame F adapted to support structural operating components globally defined by:
transportation means 2 for the step-by-step conveying the containers 1 to be filled along a horizontal determined direction D1;
two identical primary plain belt conveyors 3 and 4, arranged coupled and parallel to each other, with a single motor H1 and suitably spaced from each other, adapted to receive the products by external supply means (not shown), said belt conveyors 3 and 4 having the purpose of the products feeding parallel to said horizontal direction D1 inside the containers 1 so as to realize the main bulk filling of the containers 1;
two identical secondary small belt conveyors 5 and 6 and arranged by each other in way that to form a substantially V-shaped conveyor (see
motion means 7 applied to both principal 3 and 4 and secondary 5 and 6 belt conveyors for reciprocating moving “in translation” said aforementioned principal 3 and 4 and secondary 5 and 6 belt conveyors in a direction D2 parallel to the horizontal direction D1;
two subsequent first 8 and second 9 weighing stations (see
a stop barrier-type device 10 for stopping the feeding of the products lying on said primary main belt conveyor 3 and 4, so as to allow changing the format and size of the containers 1 in correspondence of the first weighing station 8 without let the products fall down from said principal conveyor belts 3 and 4;
means 11 for height adjustment (i.e. transversal to said horizontal direction D1) of both the primary 3 and 4 and the secondary 5 and 6 belt conveyors to allow to the filling machine M to use different sizes and formats of containers 1 to be filled with the products;
control and display means 12 (i.e. software, display, touch screen etc.) for controlling the overall operations of the machine M and also in order to carry out the filling up to forty models of containers 1 of different sizes both in height and in length.
The operation steps of the machine M of the invention is the following.
The products are fed to the principal 3 and 4 and to secondary 5 and 6 belt conveyors, and the transportation means 2 move the containers 1 below said primary and secondary conveyors, therefore the main and greater bulk filling of products into the containers 1 is realized through the cited principal belt conveyors 3 and 4 and it's then achieved a first weight control at the first weighing station 8.
In correspondence of the second weighing station 9 is subsequently realized a final precise filling of singles products into the containers 1 through the secondary internal V-shaped belt conveyors 5 and 6 acting simultaneously with the primary conveyors in order to achieve a complete final filling of the containers 1 reaching a final prefixed weighing value.
Advantages of the machine M described above with respect to the known devices are: increased production speed and therefore greater potential, increased sensitivity and precision of filling process with optimal and delicate treatment of the products without any damage, improved accuracy of weighing and increased versatility.
