TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
Questa invenzione fa riferimento al campo della tecnica relativo agli strumenti ed alle macchine, intesi come carrelli elevatori a forche ed accessori per carrelli elevatori a forche, utilizzate per operazioni di carico e scarico di cassoni contenenti principalmente prodotti agricoli, quali ad esempio olive o pomodori. This invention refers to the field of the art relating to tools and machines, intended as forklift trucks and accessories for forklift trucks, used for loading and unloading of bins containing mainly agricultural products, such as olives or tomatoes.
In seguito all'industrializzazione agricola, sono divenuti sempre più funzionali e di frequente utilizzo i cassoni tipo pallet per il contenimento dei prodotti dell'agricoltura, in quanto molto capienti, ma soprattutto facilmente movibili per mezzo di carrelli elevatori a forche (16), che inforcando dal basso il cassone (12) riescono facilmente a spostarlo ed a caricarlo, ad esempio, su un autocarro per il successivo trasporto a destinazione Tav. 1 Fig. 1. Following agricultural industrialization, pallet-type containers for containing agricultural products have become increasingly functional and frequently used, as they are very capacious, but above all easily movable by means of forklift trucks (16), which by getting into the box (12) from below, they can easily move it and load it, for example, onto a truck for subsequent transport to its destination Table 1 Fig. 1.
Sempre più utilizzati, esistono differenti accessori per carrelli elevatori a forche (16), che consentono di trasformare il meccanismo di alzata delle forche (7,9), sfruttando il circuito idraulico del carrello elevatore stesso (16), tale da poter effettuare, oltre al semplice sollevamento del cassone, altre operazioni, quali ad esempio lo svuotamento della merce contenuta all'interno del cassone (12) direttamente nell'autocarro, o nel rimorchio dell'autocarro. Questo à ̈ possibile grazie a dei rovesciatori (15), che prendono il cassone (12) e lo ribaltano sino a 90º per svuotarlo completamente nell'autocarro o in altro sito Tav. More and more used, there are different accessories for forklift trucks (16), which allow to transform the fork lifting mechanism (7,9), exploiting the hydraulic circuit of the forklift itself (16), such as to be able to perform, in addition to the simple lifting of the body, other operations, such as for example emptying the goods contained inside the body (12) directly into the truck, or into the trailer of the truck. This is possible thanks to the tippers (15), which take the body (12) and overturn it up to 90 ° to empty it completely into the truck or to another site Tav.
1 Fig. 1. Il problema tecnico risiede proprio nell'afferrare saldamente, e in piena sicurezza, il cassone (12) per effettuare la manovra di rovesciamento a 90º. 1 Fig. 1. The technical problem lies precisely in grasping the body (12) firmly and in complete safety to carry out the 90º overturning maneuver.
Ad oggi esistono accessori, come forche mobili o fisse, dotate di tasche laterali, dalla quale fuoriescono degli organi di bloccaggio i quali, agendo contro le facce interne e complanari tra loro dei primi due piedi inforcati, bloccano il cassone (12) anche attraverso un ulteriore organo che scende dall'alto, per il successivo rovesciamento a 90°. To date, there are accessories, such as mobile or fixed forks, equipped with side pockets, from which locking devices protrude which, acting against the internal and coplanar faces of the first two forked feet, block the body (12) also through a another organ that descends from above, for the subsequent 90 ° overturning.
Tali soluzioni, tuttavia, non sono affatto sicure: infatti, una volta ruotato il cassone a 90º, ed avendolo bloccato solo nella parte posteriore appena inforcata, seppur dal basso e dall'alto, si avrà inevitabilmente una flessione dell'intero cassone (12) che oltre a rendere instabile la presa, poiché il cassone risulta completamente libero di muoversi nella parte anteriore, verrà sollecitato gravosamente a flessione, essendo esso schematizzabile come una trave incastrata ad un estremità ; in questo caso, infatti, il cassone (12), ruotato di 90º, risulta incastrato esclusivamente sulla parte posteriore, restando libero sull'altro lato anteriore. La manovra, quindi, risulta instabile, poco sicura ed il cassone rischia di rompersi nel tempo, in quanto sollecitato ciclicamente, a fatica, da una pericolosa flessione dell'intero cassone (12) stesso. Inoltre, l'applicazione di tali sistemi necessita il cambio di tutto l'accessorio dotato di forche proprie, non consentendo a chi ne farà uso di utilizzare le forche proprie acquistate inevitabilmente con il carrello elevatore (16) e costringendolo, quindi, ad acquista un'ulteriore coppia di forche, in dotazione con l'accessorio di presa. These solutions, however, are not at all safe: in fact, once the body has been rotated to 90 °, and having locked it only in the rear part just forked, even from the bottom and from the top, there will inevitably be a bending of the entire body (12) that in addition to making the grip unstable, since the box is completely free to move in the front part, it will be heavily stressed in bending, as it can be schematized as a beam wedged at one end; in this case, in fact, the box (12), rotated by 90º, is locked exclusively on the rear part, remaining free on the other front side. The maneuver, therefore, is unstable, unsafe and the body risks breaking over time, as it is cyclically stressed, with difficulty, by a dangerous bending of the entire body (12) itself. Furthermore, the application of these systems requires the change of all the accessories equipped with their own forks, not allowing those who will use them to use their own forks purchased inevitably with the forklift (16) and therefore forcing them to buy a 'additional pair of forks, supplied with the gripping accessory.
L'oggetto presentato da questo brevetto propone un bloccacassone, con bracci a forchetta, per forche di carrello elevatore e rovesciatori che consente la presa del cassone allargando le forche di presa a V e bloccando, cosi, contemporaneamente i quattro piedi del cassone, caratterizzato da: The object presented by this patent proposes a box lock, with fork arms, for forklift forks and tippers which allows the gripping of the container by widening the V-shaped gripping forks and thus blocking, at the same time, the four feet of the container, characterized by :
- una piastra di supporto per portaforche (1), montabile sul carrello elevatore (16) o sul rovesciatore (15), sul quale sono fissate le traverse portaforche (2,3) lav. 1 Fig. 2; - due occhielli (4,5) solidali alla piastra di supporto per portaforche (1), posti alle estremità laterali della piastra di supporto per portaforche (1) e posizionati in maniera sfalsata fra le traverse portaforche (2,3), con i piani dei fori paralleli al piano di presa delle forche (7,9) Tav. 1 Fig. 1 e Tav. 2 Fig. 3,4; - a support plate for fork carriage (1), which can be mounted on the forklift (16) or on the tipper (15), on which the fork carriage cross members (2,3) are fixed. 1 Fig. 2; - two eyelets (4,5) integral with the fork carriage support plate (1), placed at the lateral ends of the fork carriage support plate (1) and positioned staggered between the fork carriage cross members (2,3), with the planes holes parallel to the forks gripping surface (7,9) Tab. 1 Fig. 1 and Tab. 2 Fig. 3,4;
- due pistoni idraulici (8,11), incernierati su un'estremità rispettivamente agli occhielli (4,5) e all'altra estremità a due bracci a forchetta (6,10) Tav. 1 Fig. 1 e Tav. 2 Fig. 3,4; - two hydraulic pistons (8,11), hinged on one end respectively to the eyelets (4,5) and to the other end with two fork arms (6,10) Tab. 1 Fig. 1 and Tab. 2 Fig. 3.4;
- due bracci a forchetta (6,10), con il lato a forchetta in presa su ciascuna forca (7,9), incernierati rispettivamente sull'altra estremità ai pistoni idraulici (8,11) tale da formare una V, che in seguito alia corsa dei pistoni idraulici (8,11), determinerà una forza trasversale tale da allargare lateralmente le forche (7,9); l'allargamento determina una forza di presa sulla faccia interna dei piedi posteriori (14) del cassone (12) e contemporaneamente induce un momento angolare, sfruttando il gioco angolare esistente fra le traverse portaforche (2,3) e le forche (7,9), trasmesso su ciascuna forca (7,9), il quale determinerà una leggera rotazione delle forche a V che consente anche la presa delle facce anteriori interne della coppia di piedi anteriori (13) del cassone (12), per bloccare contemporaneamente tutti i quattro piedi del cassone (12) Tav. 1 Fig. 1 e Tav. 2 Fig. 3,4; - two fork arms (6,10), with the fork side gripping each fork (7,9), hinged respectively on the other end to the hydraulic pistons (8,11) such as to form a V, which subsequently at the stroke of the hydraulic pistons (8,11), it will determine a transversal force such as to widen the forks (7,9) laterally; the widening determines a gripping force on the internal face of the rear feet (14) of the body (12) and at the same time induces an angular moment, exploiting the angular play existing between the fork carriage cross-members (2,3) and the forks (7,9 ), transmitted on each fork (7,9), which will cause a slight rotation of the V-shaped forks which also allows the gripping of the internal front faces of the pair of front feet (13) of the body (12), to simultaneously lock all the four feet of the box (12) Tab. 1 Fig. 1 and Tab. 2 Fig. 3,4;
- degli agganci (17,18) per fissare opportunamente i bracci a forchetta (6,10) sulle forche (7,9), così da consentire la trasmissione della forza trasversale e del momento angolare, dai bracci a forchetta (6,10) alle forche (7,9) Tav. 1 Fig. 1 e Tav. 2 Fig. 3,4; - hooks (17,18) to suitably fix the fork arms (6,10) on the forks (7,9), so as to allow the transmission of the transverse force and angular moment, from the fork arms (6,10 ) to the forks (7,9) Tab. 1 Fig. 1 and Tab. 2 Fig. 3,4;
L'allargamento delle forche (7,9) consente un adattamento a qualsiasi tipo di cassone (14). Bloccando tutti e quattro i piedi del cassone (12) mediante la pressione che il bordo esterno delle forche (7,9) esercita sia nelle facce interne della coppia di piedi anteriori (14) che nelle facce interne della coppia di piedi posteriori (14) del cassone (12), si compie un bloccaggio completo del cassone (12) il quale, bloccato ulteriormente dall'alto, consente di effettuare il rovesciamento a 90° del cassone (12) per il successivo svuotamento della merce contenuta all'interno, in tutta sicurezza e senza sollecitare a flessione il cassone (12). Oltretutto, essendo i due bracci a forchetta (6,10), essi possono essere intercambiati, consentendo cosi di adoperare forche di diversa larghezza senza dover cambiare tutta la piastra di supporto per portaforche (1), semplicemente adoperando dei bracci a forchetta (6,10), con il lato a forchetta avente la stessa misura della larghezza delle forche (7,9) già in possesso di chi ha un carrello elevatore (16). The widening of the forks (7,9) allows adaptation to any type of body (14). Blocking all four feet of the body (12) by means of the pressure that the external edge of the forks (7,9) exerts both in the internal faces of the pair of front feet (14) and in the internal faces of the pair of rear feet (14) of the box (12), a complete locking of the box (12) is carried out which, further blocked from above, allows to carry out the 90 ° overturning of the box (12) for the subsequent emptying of the goods contained inside, in completely safe and without bending the body (12). Moreover, being the two fork arms (6,10), they can be interchanged, thus allowing to use forks of different widths without having to change the whole fork carriage support plate (1), simply by using fork arms (6, 10), with the fork side having the same measurement as the width of the forks (7,9) already in possession of those who have a forklift truck (16).
I due bracci a forchetta (6,10) in seguito all'allargamento o restringimento a V determinata dalla corsa dei pistoni idraulici (8,11), allargano o restringono le forche (7,9) adattandosi alla presa di qualsiasi tipo di cassone (14) o pallet, rendendo il bloccacassone molto versatile ed evitando di dover acquistare un nuovo accessorio di presa, come accadeva in precedenza. The two fork arms (6,10) following the V-shaped widening or narrowing determined by the stroke of the hydraulic pistons (8,11), widen or narrow the forks (7,9) adapting to the grip of any type of body ( 14) or pallets, making the box lock very versatile and avoiding the need to purchase a new gripping accessory, as happened previously.
