DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to an automatic operating machine and in particular for drilling and milling glass plates having different shapes and sizes.


BACKGROUND OF THE PRIOR ART

Machines for automatic drilling glass plates having different shapes and sizes are known, and comprise substantially a plurality of horizontal rotating rollers mounted on a support structure and provided for supporting slidably the different glass plates to be drilled at established positions thereof, in which structure one or more drilling units are also mounted, which are formed by a set of aligned drills operated by a numerical control system provided with computer and which can be set through a proper software program, so as to regulate in advance the position and size of the holes to be made on the respective glass plates.
However, these drilling machines have the drawbacks that they are made with considerable overall dimensions because of the extent in a horizontal direction thereof and being able to perform only automatic drilling operations on the glass plates and being not able to perform possible automatic machinings of any other type such as for example the forming of through or blind cavities having different shapes and sizes and at different positions on the glass plates, since in these cases the machinings referred to must be performed necessarily with special manual operations, with consequent lower productivity and possibility to damage the glass plates on which such additional machining operations are performed.


SUMMARY OF THE INVENTION

The present invention has the object to eliminate the above mentioned drawbacks, by means of an automatic operating machine and in particular for drilling and milling glass plates having different shapes and sizes, which is made in a manner to permit not only to drill but also to perform machinings of other kind such as for example to perform openings having different shapes and sizes on the glass plates, wherein such machine is set for machining the plates by arranging them at a vertical or sligthly inclined direction, in a way to obtain a high operative capacity with compact and reduced overall dimensions of the same machine.


BRIEF DESCRIPTION OF THE DRAWINGS

The characteristics and advantages obtained with the machine in accordance to the invention will be evident from the following description, by way of a not limitative example only and with reference to the accompanying drawings, wherein:
FIG. 1 shows a schematic front view of the drilling and milling machine according to the invention;
FIG. 2 shows a perspective front view of the machine of FIG. 1;
FIG. 3 shows a schematic plan view of the machine of FIG. 1;
FIG. 4 shows a partial side view of a constructive item of the machine according to the invention;
FIG. 5 shows a perspective side view of another constructive item of the machine according to the invention;
FIG. 6 shows a glass plate with some machining operations which can be performed onto it by means of the present machine.
In the Figures referred to, it is represented schematically a machine adapted to perform the automatic drilling and milling of glass plates having different shapes and sizes, and in particular for providing holes or openings onto them having different size, configuration and positioning.
By referring particularly to the FIGS. 1-3, it is noted that the machine referred to is constituted substantially by a lengthened rectilinear support structure 10, formed by a horizontal extended base 11 joined to an orthogonal rest surface 12 having vertical or sligtly inclined extent, and at least one fixedly secured drilling and milling unit 13 formed by a single support structure 14 onto which at least two carriages 15 and 16 identical and opposite symmetrically from each other are mounted, which carriages are slidable reciprocatingly along correspondent vertical guide members (not shown) provided on the support structure 14 and arranged in correspondence of the opposite rectilinear surfaces of the rest surface 12 as well as provid
