"Machine for cleaning glass panes"

Italian priority of August 29, 1969 from Italian patent application No. 33623 A / 69

The cleaning of the glass panes of windows and doors or the cleaning of shop windows is usually done by hand or with the help of rotating cleaning machines that require a lot of space and for the most diverse Purposes were developed. When cleaning glass panes, the use of these rotary machines brings a number of benefits disadvantages, the most important of which are briefly mentioned below:

a) While these machines are in use, the respective operator cannot hold them steady or point them Tendency to move in all directions, a fact that is due to the friction of the soft disc on the upper: surface of the glass plate is due. !

b) On the surface of the glass pane let the rotation f movement remaining traces of the polishing felt and the rubbing; ugly reflexes arise.

c) Finally, the disadvantage should be mentioned that with the previously, known machines, the edges located directly on the frame are not included in the cleaning process can.

The purpose of the invention is therefore to create a machine equipped with felt buffers for cleaning glass sheets.

ben, which are particularly suitable for use on window panes, glazing, Lead glass windows and display windows is suitable. The essential feature of the machine constructed according to the invention for cleaning glass windows is the multitude of felt buffers of different profiles, which are symmetrical and converging Directions are set in an alternating motion in such a way that the resultant of the inertial forces and that of the felt buffers self-generated frictional forces practically equates to a cancellation of these forces. The resulting synchronism and the fact that the machine is vibration-free enables easy handling even by inexperienced workers. Through the various Shapes of the swinging felt buffers result in the possibility of cleaning the glass edges at the respective Bezels.

In the accompanying drawings is constructed according to the invention Machine for cleaning glass plates illustrated schematically on the basis of some exemplary selected embodiments. Show it:

- Fig. 1 - a perspective partial sectional view of the machine;

- Fig. 2 - a side view in partial section of the same Machine; ;

- Fig. 3 - a perpendicular cross-sectional view of the

same machine;

- Fig. H - a plan view of the lower part of the machine and _;

- Fig. 5 - a variant with a special arrangement of the drive motor and the associated mechanical parts. \

In the drawings, a base plate is shown at 1, on which the drive motor 2 and the handle 3 befe- i are stigt. The drive motor 2 is via the line 3a 2a); fed with alternating current. Said base plate 1 is after continued at the bottom by two rectangular plates M- on each of which > Because small joints 5 are attached as brackets.

The drive shaft 7 of the motor 2 is an air duct 8 which, among other tasks, has a cooling function, and a gear pinion 9 put on. ·

This gear pinion 9 engages in two tooth crowns 10 which are symmetrically arranged and run on two axes 11 which are guided in the plate 1, with an offset eccentric pin 12 also being provided. These eccentric pins 12 drive the plates 4 via the rods 13 with a animal movement. The arrangement of the rod ends and the pins on the tooth crowns is chosen so that the plates are driven in opposite directions in an alternating movement if they are precisely balanced. FIG. 5 shows in detail the transmission of movement with the motor lying horizontally, specifically via the connection between toothed crown 14 and worm 15, with the other moving members standing still. It should be pointed out here that the plates H, instead of being suspended on the rods, can be slidably guided in rails specially provided for this purpose, which were not shown in this example. In addition, the oscillating movement to the felt buffers can be ^{transmitted via 1} double-tensioned squat or via a combined cam / spring syntein.

It is taken for granted that the individual parts given Derivable Variant also form part of the invention.

Claims (1)

o ** 2UA2 UO DIETRICH LEWINSKY ^ 25 Aug 1970 PATENT ADVOCATE 62 6232 - V. Alfiero TONINI, Marina di Pisa, Via Barbolani (Italy) Patent claims: Machine for cleaning glass panes, characterized in that it consists of several felt buffers (6) of different profiles, which are designed as oscillating buffers and are set in an alternating movement symmetrically and in converging directions in such a way that the resultant of the inertial forces and that of the felt buffers themselves Frictional forces generated practically equates to a cancellation of these forces. Machine for cleaning glass panes according to Claim 1, characterized in that each of the felt buffers (6) is attached to small Joints (5) are suspended, which run in rails or that these felt buffers are suspended from other parts of the machine that allow the required degree of freedom. Machine for cleaning glass panes according to claim 1 or 2, characterized in that each felt buffer (6) is guided over a rod (13) in such a way that the felt buffer is in ^; an oscillating movement is displaced. Machine for cleaning glass panes according to one of the aforementioned Claims, characterized in that each felt buffer (6) with a single or double clamped cam in the Form is guided that the felt buffer is set in an oscillating motion. Machine for cleaning glass panes according to one of the aforementioned Claims, characterized in that the cams or rods (13) are guided over toothed crowns (10) which reduce the speed of the electric drive motor (2) accordingly. 109810/0306 Blank page
