SISTEMA PER IL BLOCCAGGIO AMOVIBILE DI UN UTENSILE AD UN RELATIVO SUPPORTO IN MACCHINE PER LA RECISIONE DI ARTICOLI. SYSTEM FOR THE REMOVABLE LOCKING OF A TOOL TO A RELATIVE SUPPORT IN MACHINES FOR THE RECISION OF ARTICLES.

DESCRIZIONE DELL'INVENZIONE DESCRIPTION OF THE INVENTION

La presente invenzione si inserisce nel settore tecnico concernente il sistema per il bloccaggio di un utensile ad un relativo supporto in macchine per la recisione di articoli. The present invention is part of the technical sector concerning the system for locking a tool to a relative support in machines for cutting articles.

In particolare si considerano quelle macchine in cui l'articolo da recidere viene steso su un piano di lavoro e bloccato a questo, per essere tagliato, secondo sagome predefinite, da una lama associata ad una testa operativa, azionata verticalmente con moto alternato. In particular, we consider those machines in which the article to be cut is laid out on a work surface and locked to it, to be cut, according to predefined shapes, by a blade associated with an operating head, operated vertically with reciprocating motion.

La testa operativa à ̈ provvista di un supporto a cui viene bloccata la lama; in tale soluzione la posizione assiale della lama, e il suo corrispondente bloccaggio, à ̈ demandata al fissaggio di quest'ultima al supporto. The operating head is provided with a support to which the blade is locked; in this solution the axial position of the blade, and its corresponding locking, is left to the fixing of the latter to the support.

Per tale bloccaggio amovibile à ̈ previsto un foro centrale passante nella lama e almeno un organo per il fissaggio della lama al supporto. For this removable locking there is a central through hole in the blade and at least one organ for fixing the blade to the support.

Durante le operazioni di recisione degli articoli si può verificare una variazione assiale della lama causata, ad esempio, dall'allentamento dell'organo di fissaggio il che per le tolleranze tra quest'ultimo ed il foro assiale della lama provoca il citato disassamento, con tutti gli inconvenienti e le problematiche che ne derivano. During the cutting operations of the articles, an axial variation of the blade may occur, caused, for example, by the loosening of the fastening element which, due to the tolerances between the latter and the axial hole of the blade, causes the aforementioned misalignment, with all the inconveniences and the problems that derive from it.

La prerogativa della presente invenzione à ̈ quella di proporre un sistema per il bloccaggio amovibile di un utensile ad un relativo supporto in macchine per la recisione di articoli che permetta di centrare perfettamente l'utensile rispetto al relativo supporto e quello di mantenere il posizionamento e l'orientamento assiale dello stesso utensile durante le operazioni di recisione di articoli. The prerogative of the present invention is to propose a system for the removable locking of a tool to a relative support in machines for cutting articles that allows to perfectly center the tool with respect to the relative support and to maintain the positioning and the axial orientation of the same tool during article cutting operations.

Un'altra prerogativa dell'invenzione à ̈ quella di proporre un sistema per il bloccaggio amovibile di un utensile al relativo supporto, di semplice concezione che consenta un semplice e veloce posizionamento dello stesso utensile. Another prerogative of the invention is that of proposing a system for the removable locking of a tool to the relative support, of simple design which allows a simple and fast positioning of the same tool.

Ancora una prerogativa dell'invenzione à ̈ quella di proporre un sistema che oltre a soddisfare le prerogative di cui sopra permetta il solo utilizzo di un utensile e del corrispondente supporto, ad aumentare le caratteristiche tecnico-funzionali di recisione delle macchine a cui tale supporto à ̈ associato. Another prerogative of the invention is to propose a system which, in addition to satisfying the aforementioned prerogatives, allows only the use of a tool and the corresponding support, to increase the technical-functional characteristics of cutting of the machines to which this support is ̈ associate.

Tali prerogative sono ottenute in accordo con quanto riportato nelle rivendicazioni. Le caratteristiche dell’invenzione sono evidenziate nel seguito, con particolare riferimento alle unite tavole di disegno, nelle quali: These prerogatives are obtained in accordance with what is reported in the claims. The characteristics of the invention are highlighted below, with particular reference to the accompanying drawing tables, in which:

- la fig.1 illustra una vista in prospettiva di un supporto per un utensile in macchine per la recisione di articoli; - Fig. 1 illustrates a perspective view of a support for a tool in machines for cutting articles;

- la fig.2 illustra una vista frontale di un utensile per la recisione di articoli; - fig. 2 shows a front view of a tool for cutting articles;

- la fig.3 illustra una vista in prospettiva del complesso supporto-utensile; - Fig. 3 shows a perspective view of the support-tool assembly;

- la fig.4 illustra una vista frontale di quanto illustrato in fig.3. - fig. 4 shows a front view of what is illustrated in fig. 3.

Con riferimento alle allegate tavole di disegno si à ̈ indicato con 1 un supporto, da associare ad una testa operativa, non illustrata, parte integrante di una macchina per il taglio di pellame e similari, anch'essa non illustrata, e con il riferimento 2 un utensile, nel particolare una lama. With reference to the attached drawing tables, 1 indicates a support, to be associated with an operating head, not illustrated, an integral part of a machine for cutting leather and the like, also not illustrated, and with reference 2 a tool, in particular a blade.

Il supporto 1 Ã ̈ costituito da un elemento di aggancio 10 (parzialmente illustrato nelle tavole di disegno), da associare in modo noto alla testa operativa della macchina, che conforma un organo porta-lama 11. The support 1 consists of a hooking element 10 (partially illustrated in the drawing tables), to be associated in a known way to the operating head of the machine, which forms a blade holder 11.

L'organo porta-lama 11, come illustrato in fig.1, Ã ̈ interessato da un alloggiamento 12, di larghezza non inferiore alla larghezza della lama 2, ad esempio sagomato, ad individuare due pareti contrapposte 12a, 12b, rispettivamente prima e seconda, con quest'ultima di lunghezza inferiore rispetto alla prima. The blade holder 11, as illustrated in fig. 1, is affected by a housing 12, with a width not less than the width of the blade 2, for example shaped, to identify two opposite walls 12a, 12b, respectively first and second , with the latter being shorter than the former.

Dalla prima parete 12a si sviluppa, trasversalmente e ad una distanza predefinita dalla porzione terminale 110 dell'organo porta-lama 11, un innesto 14. From the first wall 12a a coupling 14 extends transversally and at a predefined distance from the end portion 110 of the blade holder 11.

Il fondo 12c dell'alloggiamento 12 Ã ̈ interessato, ad una distanza "d" dal bordo della porzione terminale 110, da un foro passante 15. The bottom 12c of the housing 12 is affected, at a distance "d" from the edge of the terminal portion 110, by a through hole 15.

Alla facciata esterna della seconda parete 12b à ̈ solidale un perno 16 che supporta in folle un cuscinetto antirotazione 17 mobile, in seguito alle operazioni di taglio, lungo una corrispondente guida, non illustrata. Integral to the external face of the second wall 12b is a pin 16 which idly supports an anti-rotation bearing 17 which is movable, following the cutting operations, along a corresponding guide, not shown.

La porzione terminale 110 dell'organo porta-lama à ̈ interessata da un'apertura 18 comunicante con l'alloggiamento 12 di cui sarà nel seguito esplicata la funzione. La lama 2, secondo caratteristiche note, ha forma di un parallelogramma, à ̈ dotata di un foro centrale F e, come illustrato a titolo di esempio nella fig. 2, à ̈ provvista, in corrispondenza dei lati obliqui corti, di due taglienti T1, T2. The terminal portion 110 of the blade-holding member is affected by an opening 18 communicating with the housing 12, the function of which will be explained hereinafter. The blade 2, according to known characteristics, has the shape of a parallelogram, is equipped with a central hole F and, as illustrated by way of example in fig. 2, is provided, in correspondence of the short oblique sides, with two cutting edges T1, T2.

I lati lunghi 2a, 2b, di detta lama 2 sono rispettivamente interessati, ad una distanza "K" dalla punta P di ogni tagliente T1, T2, da una corrispondente sede R. Come illustrato nelle figure 3, 4, la lama 2 viene posizionata nell'alloggiamento 12 dell'organo porta-lama 11, in modo tale da definire il mutuo accoppiamento tra l'innesto 14 e la sede R prevista su uno dei due lati lunghi 2a, 2b di detta lama 2, con parte delle rispettive facciate dei lati lunghi di quest'ultima a riscontrare la rispettiva prima e seconda parete 12a, 12b. The long sides 2a, 2b of said blade 2 are respectively involved, at a distance "K" from the tip P of each cutting edge T1, T2, from a corresponding seat R. As shown in Figures 3, 4, the blade 2 is positioned in the housing 12 of the blade-holding member 11, in such a way as to define the mutual coupling between the graft 14 and the seat R provided on one of the two long sides 2a, 2b of said blade 2, with part of the respective faces of the long sides of the latter to abut the respective first and second walls 12a, 12b.

Con tale posizionamento il foro F della lama 2 Ã ̈ coassiale con il foro passante 15 previsto nell'organo porta-lama 11, e, come illustrato in fig. 3, il tagliente T2 della lama 2 fuoriesce dall'apertura 18 per poter recidere l'articolo in seguito all'azionamento della macchina per la recisione a cui detto complesso supporto 1lama 2 Ã ̈ bloccato. With this positioning, the hole F of the blade 2 is coaxial with the through hole 15 provided in the blade holder 11, and, as illustrated in fig. 3, the cutting edge T2 of the blade 2 protrudes from the opening 18 in order to be able to sever the article following the actuation of the cutting machine to which said assembly support 1 blade 2 is locked.

Si stabilizza, successivamente, tale mutuo accoppiamento con l'inserimento di idonei noti mezzi di fissaggio, non illustrati, in detti foro F e foro passante 15. This mutual coupling is subsequently stabilized with the insertion of suitable known fastening means, not illustrated, in said hole F and through hole 15.

Il sistema descritto per il bloccaggio della lama 2 ad un relativo supporto in macchine per la recisione di articoli presenta caratteristiche particolarmente vantaggiose. The described system for locking the blade 2 to a relative support in machines for cutting articles has particularly advantageous characteristics.

Il mutuo accoppiamento tra l'innesto 14 e la sede R, in seguito al posizionamento e stabilizzazione della lama 2 all'organo porta-lama 11, risulta vantaggioso, in quanto viene garantito il corretto posizionamento della lama 2 rispetto all'organo porta-lama e si evitano eventuali variazioni della posizione e dell'orientamento assiale della lama 2 rispetto all'organo porta-lama 11, in seguito alle operazioni di recisione di articoli. The mutual coupling between the graft 14 and the seat R, following the positioning and stabilization of the blade 2 to the blade holder 11, is advantageous, since the correct positioning of the blade 2 with respect to the blade holder is guaranteed. and any variations in the position and axial orientation of the blade 2 with respect to the blade holder 11 are avoided, following the cutting operations of articles.

Il fatto di prevedere in ogni lato lungo 2a, 2b, della lama 2 una sede R ad una distanza "K" dalla punta P di ogni tagliente T1, T2, permette di rovesciare la lama rispetto all'organo porta-lama in seguito all'usura di uno di detti taglienti T1, T2. Si disinseriscono i mezzi di bloccaggio dal foro F e dal foro passante 15, si estrae la lama 2 dall'alloggiamento 12, si rovescia la lama 2 e la si posiziona nuovamente nell'alloggiamento 12, in modo tale che la sede R prevista sull'altro lato lungo della lama 2 si accoppi mutuamente con l'innesto 14; si provvede, quindi, a bloccare il suddetto mutuo accoppiamento come descritto precedentemente. The fact of providing in each long side 2a, 2b of the blade 2 a seat R at a distance "K" from the tip P of each cutting edge T1, T2, allows the blade to be overturned with respect to the blade-holding member following the wear of one of said cutting edges T1, T2. The locking means are removed from the hole F and the through hole 15, the blade 2 is extracted from the housing 12, the blade 2 is overturned and it is positioned again in the housing 12, so that the seat R provided on the another long side of the blade 2 is mutually coupled with the graft 14; the aforesaid mutual coupling is then blocked as previously described.

Il fatto di associare alla testa operativa di note macchine per la recisione di articoli il complesso supporto 1-lama 2, realizzato come precedentemente descritto, risulta vantaggioso, in quanto con l'utilizzo di tale complesso aumentano le caratteristiche tecnico-funzionali legate alla precisione di recisione degli articoli. Si intende che quanto sopra à ̈ stato descritto a titolo esemplificativo, e non limitativo, per cui eventuali variazioni di natura pratico applicativa si intendono rientrare nell’ambito protettivo come sopra descritto e nel seguito rivendicato. The fact of associating the support 1-blade 2 assembly, realized as previously described, to the operating head of known machines for cutting articles is advantageous, since with the use of this assembly the technical-functional characteristics linked to the precision of cutting of the articles. It is understood that what above has been described as an example, and not a limitation one, therefore any variations of a practical applicative nature are intended to fall within the protective scope as described above and claimed hereinafter.
