Descrizione dell'invenzione avente per titolo: Description of the invention entitled:
"DISPOSITIVO A DISCO TERMICO PER MACCHINE LUCIDATRICI MONOSPAZZO-LA" "THERMAL DISC DEVICE FOR SINGLE-SPACE POLISHING MACHINES-LA"
La presente invenzione si riferisce ad un dispositivo a disco termico per macchine monospazzola per la lucidatura ed il lavaggio a caldo di superfici, particolarmente di pavimenti. The present invention relates to a thermal disc device for single brush machines for polishing and hot washing surfaces, particularly floors.
E' ben noto nella tecnica di usare macchine lucidatrici monospazzola per effettuare le operazioni di lucidatura e di lavaggio dei pavimenti o di altre superfici, con l'aiuto di sostanze chimiche in pasta o liquide. E' altresì noto che dette operazioni vengono realizzate con maggior successo fornendo calore alla superficie di lucidatura, praticamente per tutti i tipi di pavimento, (compresi quelli in linoleum e ad eccezione di quelli in materiali termoplastici), anche se i risultati più interessanti si ottengono su marmi e graniti. It is well known in the art to use single-brush polishing machines to carry out the operations of polishing and washing floors or other surfaces, with the help of chemical substances in paste or liquid form. It is also known that these operations are carried out with greater success by supplying heat to the polishing surface, practically for all types of flooring, (including those in linoleum and with the exception of those in thermoplastic materials), even if the most interesting results are obtained on marble and granite.
Al momento presente, esistono macchine lucidatrici monospazzola che utilizzano dispositivi di alimentazione del calore in cui il disco viene riscaldato dall'esterno mediante soffianti di aria calda, che dirigono assialmente al centro il calore, che poi si propaga radialmente per tutto il disco. In altre realizzazioni viene utilizzato come sorgente di calore l'attrito generato dal contatto tra il disco di lucidatura rotante ed un disco fisso o diversamente ruotante ad esso associato faccia a faccia. Entrambi i detti dispositivi di alimentazione del calore presentano evidenti problemi: in termini di eccessivo ingombro dimensionale e di ridotta efficienza nel primo caso, di rapida usura dei dischi, nel secondo caso, di elevato consumo di energia in entrambi. At the present time, single-brush polishing machines exist that use heat supply devices in which the disc is heated from the outside by hot air blowers, which axially direct the heat to the center, which then spreads radially throughout the disc. In other embodiments, the friction generated by the contact between the rotating polishing disc and a fixed or otherwise rotating disc associated with it face to face is used as a source of heat. Both said heat supply devices have obvious problems: in terms of excessive dimensional bulk and reduced efficiency in the first case, rapid wear of the discs, in the second case, high energy consumption in both.
Scopo della presente invenzione è di fornire un dispositivo a disco termico che viene riscaldato in modo diffuso ed efficace con un consumo di energia relativamente basso e che presenta un ingombro relativamente ridotto. The object of the present invention is to provide a thermal disc device which is heated in a diffuse and effective manner with a relatively low energy consumption and which has a relatively small footprint.
Secondo un primo, essenziale aspetto della presente invenzione, si fornisce un dispositivo a disco termico per macchine lucidatrici monospazzola caratterizzato dal fatto che è composto da un disco di lucidatura rotante e da un disco fisso ad esso associato faccia a faccia, fatto di materiale termicamente buon conduttore, in cui è inglobata una resistenza elettrica opportunamente alimentata, sulla superficie di contatto tra il disco di lucidatura ed il disco fisso venendo disposto grasso al silicone per assicurare la lubrificazione e favorire il passaggio di calore, mantenendo minima la distanza tra i due dischi. According to a first, essential aspect of the present invention, a thermal disc device is provided for single disc polishing machines characterized in that it is composed of a rotating polishing disc and a fixed disc associated with it face to face, made of thermally good material. conductor, in which a suitably powered electrical resistance is incorporated, on the contact surface between the polishing disc and the fixed disc, silicone grease is placed to ensure lubrication and facilitate the passage of heat, keeping the distance between the two discs minimum.
Secondo un ulteriore aspetto della presente invenzione, uno strato di materiale isolante termico, per esempio gommaspugna, viene inserito come un’intercapedine tra detto disco fisso ed un carter freddo che riveste superiormente l'intero dispositivo. According to a further aspect of the present invention, a layer of thermal insulating material, for example sponge rubber, is inserted as a gap between said fixed disk and a cold casing that covers the entire device at the top.
Si descrive ora in maggior dettaglio l'invenzione, facendo riferimento al disegno allegato di una sua forma d'esecuzione attualmente preferita, figura che è una vista ih sezione trasversale assiale di una macchina lucidatrice monospazzola equipaggiata con il disco termico secondo l'invenzione. The invention is now described in greater detail, with reference to the attached drawing of a currently preferred embodiment thereof, which is an axial cross-sectional view of a single-brush polishing machine equipped with the thermal disc according to the invention.
Nella lucidatrice secondo la figura un disco di lucidatura rotante 1 è collegato all'albero 2 di un motore di azionamento non mostrato per mezzo di viti 3 ed è montato tramite cuscinetti 4 che ne consentono la rotazione rispetto ad un disco fisso 5, cui è associato, con le rispettive superfici circolari affacciate e strettamente ravvicinate. Detto disco fisso 5 è composto di materiale buon conduttore di calore e porta inglobata una resistenza elettrica 6, controllata da un termoregolatore 7 e alimentata dalla rete attraverso un cavo 8. Interposto tra il disco fisso 5 ed un carter freddo 9, che riveste superiormente l'intero dispositivo, è previsto uno strato di materiale isolante 10, per esempio di gommaspugna, che isola termicamente il dispositivo a disco termico dal carter e dal motore. Distanziali li mantengono costante lo spessore dello strato di materiale isolante 10 e rendono solidale il disco fisso 5 al carter freddo 9. Una staffa 12 collega il dispositivo a disco termico al complesso della macchina lucidatrice monospazzola, che comprende, in modo noto, anche una leva 13 di manovra e una ruota 14 per gli spostamenti in condizioni non operative della macchina. In the polisher according to the figure, a rotating polishing disc 1 is connected to the shaft 2 of a drive motor not shown by means of screws 3 and is mounted by means of bearings 4 which allow it to rotate with respect to a fixed disc 5, to which it is associated , with the respective circular surfaces facing and closely close together. Said fixed disk 5 is composed of a good heat conductor material and carries an incorporated electrical resistance 6, controlled by a thermoregulator 7 and powered by the network through a cable 8. Interposed between the fixed disk 5 and a cold casing 9, which covers the upper part of the For the entire device, a layer of insulating material 10 is provided, for example foam rubber, which thermally insulates the thermal disc device from the crankcase and from the engine. Spacers keep them constant the thickness of the layer of insulating material 10 and make the fixed disc 5 integral with the cold casing 9. A bracket 12 connects the thermal disc device to the whole of the single disc polishing machine, which also includes, in a known way, a lever 13 for maneuvering and a wheel 14 for moving the machine in non-operating conditions.
Al momento del montaggio si dispone sulla superficie di contatto tra il disco di lucidatura rotante 1 ed il disco fisso 5 uno strato consistente di grasso al silicone per assicurare la lubrificazione e favorire il passaggio di calore, mantenendo minima la distanza tra i due dischi. At the time of assembly, a consistent layer of silicone grease is placed on the contact surface between the rotating polishing disc 1 and the fixed disc 5 to ensure lubrication and facilitate the passage of heat, keeping the distance between the two discs at a minimum.
Può essere inoltre previsto un termostato di sicurezza che entra in funzione nel caso di guasto al termoregolatore 7. A safety thermostat can also be provided which comes into operation in the event of a fault in the thermoregulator 7.
