Nello stato atuale della tecnica di movimentazione di pedane per parcheggi automatici negli assi X Y siamo di fronte a meccanismi complessi pesanti e con molte lavorazioni meccaniche. In the current state of the art of handling platforms for automatic parking lots in the X Y axes, we are faced with complex mechanisms that are heavy and with many mechanical processes.

Lo scopo di quest'invenzione Ã ̈ quella di utilizzare un semplice meccanismo di spostamento pedane X Y, avere poche lavorazioni meccaniche e i pesi contenuti. The purpose of this invention is to use a simple X Y platform movement mechanism, to have few mechanical processes and low weights.

Il meccanismo di movimentazione delle pedane oggetto di quest'invenzione (Fig.3) Ã ̈ definito da tre assiemi, la rete dei binari (Fig. 1) (1) e (Fig. 3) (3, 4), il gruppo centrale di movimento (Fig. 3) (27) e (Fg.13) con le ruot di frizione (12) e la pedana di supporto vettur (Fig. 1, 2) (2) e (Fig. 10) con le guide (8, 9, 10, 11). The movement mechanism of the platforms object of this invention (Fig. 3) is defined by three assemblies, the track network (Fig. 1) (1) and (Fig. 3) (3, 4), the central group movement (Fig. 3) (27) and (Fg.13) with the friction wheels (12) and the carrier support platform (Fig. 1, 2) (2) and (Fig. 10) with the guides ( 8, 9, 10, 11).

Per muovere la pedana in X il gruppo centrale (Fig. 2) (27) muovendosi verticalmente verso l'alto tramite un quadrilatero articolato (Fig. 2, 13) (17, 18, 19, 20, 21) fornendo aria in pressione ai pistoni (22) imprime una forza tramite le ruote di frizione (12) sulle guide sotto la pedana (Fig. 2, 10) (8, 9) e (Fig. 7) (9) che abbinata alla loro rotazione ne produce la traslazione della pedana (Fig. 1) e delle gambe (25) che la sostengono lungo i binari (1), su ciascuna gamba Ã ̈ presente una sfera portante a ricircolo di sfere (Fig. 9) (6) con assialmente un cuscinetto a sfere (7) per guidare in modo fluido la pedana (2) sui binari (1) sia in X sia in Y. To move the platform in X, the central group (Fig. 2) (27) moving vertically upwards through an articulated quadrilateral (Fig. 2, 13) (17, 18, 19, 20, 21) supplying pressurized air to the pistons (22) impresses a force through the friction wheels (12) on the guides under the platform (Fig. 2, 10) (8, 9) and (Fig. 7) (9) which, combined with their rotation, produces their translation of the platform (Fig. 1) and of the legs (25) that support it along the tracks (1), on each leg there is a ball bearing ball (Fig. 9) (6) with axially a ball bearing (7) to smoothly guide the platform (2) on the tracks (1) both in X and in Y.

Per muovere la pedana in Y, tramite una gestione elettronica con PLC del motore abbinata a dei sensori "proximity" (Fig. 13) (16) presenti in asse sul gruppo centrale (Fig. 13) quando le gambe della pedana (Fig. 8, 9, 10) (6, 7, 25) si trovano in prossimitÃ degli incroci (Fig. 8) fermo la rotazione delle ruote di frizione faccio uscire l'aria dai pistoni (Fig. 13) (22) scende il gruppo centrale e le ruote di frizione (Fig. 2) (12) escono dalle guide della pedana (Fig. 2) inverto la rotazione di 90° del gruppo di movimento (Fig. 3) (27) che Ã ̈ montato sulla ralla a sfere (Fig. 2, 13) (43), fornendo aria al pistone (24) a questo punto do nuovamente aria ai pistoni (22) si alza il gruppo di movimento (Fig. 5) (27), le ruote di frizione (12) s'inseriscono nelle guide sotto la pedana perpendicolari alle precedenti (Fig, 5, 10) (10, 11) aziono il riduttore (Fig. 13) (13) e tramite le catene (15) e i pignoni (26) messi in tiro tramite dei tendicatena a vite (38), movimento le ruote di frizione con alto coefficiente d'attrito (12) che premendo e ruotando sulle guide sotto la pedana (2) la spostano in un'asse differente. To move the platform in Y, by means of an electronic management with PLC of the motor combined with "proximity" sensors (Fig. 13) (16) present in axis on the central group (Fig. 13) when the legs of the platform (Fig. 8) , 9, 10) (6, 7, 25) are located near the intersections (Fig. 8) when the friction wheels rotate I let the air out of the pistons (Fig. 13) (22) the central unit goes down and the friction wheels (Fig. 2) (12) come out of the guides of the platform (Fig. 2) I reverse the 90 ° rotation of the movement unit (Fig. 3) (27) which is mounted on the ball bearing (Fig. . 2, 13) (43), supplying air to the piston (24) at this point, giving air to the pistons (22) again, the movement unit (Fig. 5) (27) rises, the friction wheels (12) s '' insert in the guides under the platform perpendicular to the previous ones (Fig, 5, 10) (10, 11) I activate the reducer (Fig. 13) (13) and by means of the chains (15) and the pinions (26) placed in tension by means of screw chain tensioner (38), movement of the clutch wheels one with high coefficient of friction (12) which by pressing and rotating on the guides under the platform (2) move it in a different axis.

La complessitÃ del movimento delle pedane nei binari e stata ridotta eliminando, di fatto, il possibile uso di Scambi meccanici di direzione. The complexity of the movement of the platforms on the tracks has been reduced by effectively eliminating the possible use of Mechanical Direction Switches.

E' stata posta particolare attenzione alla riduzione delle lavorazioni meccaniche di componenti cercando di adottare tutta componentistica commerciale, profili a UNP(3), piatto acciaio temperato (5), sfera portante a ricircolo di sfere(6), cuscinetto a sfere standard (7), ruote di frizione (12), riduttore senza fine (13), motore elettrico azionato da inverter (14), catena maglia singola standard (15), pignoni 1⁄2"-5/16" 20 denti (26) Sensore proximity standard (16), pistoni classe 61 -50 corsa 50 (22), pistoni classe 61 -32 corsa 300 (24), Ralla a sfere (43), angolare (31), Viti a bottone M8 (32), Lamiera grecata (33), supporto per cuscinetto albero da 40 mm (34), boccole autolubrificanti (39) e usando lamiere tagliate al laser e piegate (8, 17, 18, 20, 23, 29,30) e alberi meccanici ricavati da trafilati (Fig. 13) (35, 36, 40, 41). Particular attention has been paid to the reduction of mechanical machining of components, trying to adopt all commercial components, UNP profiles (3), hardened steel plate (5), recirculating ball bearing ball (6), standard ball bearing (7 ), friction wheels (12), endless reduction gear (13), electric motor driven by inverter (14), standard single link chain (15), 1⁄2 "-5/16" 20 tooth sprockets (26) Proximity sensor standard (16), pistons class 61 -50 stroke 50 (22), pistons class 61 -32 stroke 300 (24), Ball washer (43), angular (31), M8 button screws (32), Corrugated sheet ( 33), support for 40 mm shaft bearing (34), self-lubricating bushings (39) and using laser-cut and bent sheet metal (8, 17, 18, 20, 23, 29,30) and mechanical shafts made from drawn (Fig . 13) (35, 36, 40, 41).

I pesi della struttura dei binari sono contenuti sfruttando che questo tipo d'impianti Ã ̈ montato su pavimentazioni - solai in bolla e con elevata portata al m<Î›>2 trattandosi in genere di gettate di cemento armato. The weights of the track structure are contained by exploiting the fact that this type of systems is mounted on floors - level floors with a high capacity of m <Î ›> 2, as these are generally reinforced concrete castings.

Si Ã ̈ utilizzato un U con degli angolari forati saldati lateralmente (Fig. 8) (3, 4, 31) per il suo ancoraggio tramite tasselli al pavimento (Fig. 6, 9) (42). A U was used with perforated angles welded laterally (Fig. 8) (3, 4, 31) for its anchoring to the floor by means of dowels (Fig. 6, 9) (42).

I binari che costruiscono la rete di spostamento (Fig. 1) (1) delle pedane (2) sono di due tipi e di misure differenti (Fig. 6) (3, 4) secondo il layout dove sarÃ posizionata la rete, il primo tipo tagliato dritto(4) e il secondo con le ali scantonate (3). The tracks that build the displacement network (Fig. 1) (1) of the platforms (2) are of two types and of different sizes (Fig. 6) (3, 4) according to the layout where the net will be positioned, the first straight cut type (4) and the second with notched wings (3).

All'interno dei binari (3, 4) Ã ̈ montato un piatto d'acciai temperato (5) con le stesse caratteristiche dell'acciaio per cuscinetti con limite a fatica dell'ordine di 800 N/mm<Î›>2 e una durezza superficiale che supera i 55 HRC, bloccato da delle graffe avvitate sull'U (32, 37), il piatto serve a diminuire l'attrito di scorrimento delle sfere portanti creando, di fatto, un cuscinetto rettilineo. Inside the tracks (3, 4) a tempered steel plate (5) is mounted with the same characteristics as the steel for bearings with a fatigue limit of the order of 800 N / mm <Î ›> 2 and a surface hardness exceeding 55 HRC, blocked by staples screwed on the U (32, 37), the plate serves to decrease the sliding friction of the bearing balls creating, in fact, a rectilinear bearing.

La pedana (Fig. 10) Ã ̈ progettata interamente in lamiera presso-piegata per ridurre il peso e le lavorazioni di saldatura (Fig, 11, 12) (28, 8), sotto la pedana sono montate due guide in lamiera piegata (8, 9, 10, 11) con una sezione particolare (Fig. 12), queste guide accoppiate con le ruote di frizione (12) permettono il moto di traslazione rettilineo X nei tratti degli incroci dove i binari sono senza ali (Fig. 8). The platform (Fig. 10) is designed entirely in bent sheet metal to reduce weight and welding operations (Fig, 11, 12) (28, 8), two folded sheet metal guides are mounted under the platform (8 , 9, 10, 11) with a particular section (Fig. 12), these guides coupled with the friction wheels (12) allow the straight translation motion X in the sections of the intersections where the tracks are without wings (Fig. 8) .
