DESCRIZIONE DESCRIPTION
dell'invenzione industriale avente per titolo: of the industrial invention entitled:
“Manipolatore a testa aspirante per uova o prodotti fragili similari†⠀ œSuction head manipulator for eggs or similar fragile productsâ €
La presente invenzione concerne un manipolatore a testa aspirante per uova o prodotti fragili similari. The present invention relates to a suction head manipulator for eggs or similar fragile products.
Allo stato attuale della tecnica, sono note macchine per la manipolazione delle uova tramite sistemi di sollevamento che utilizzano il vuoto generato da appositi aspiratori, compressori o pompe del vuoto abbinati a ventose. In the current state of the art, machines are known for handling eggs by means of lifting systems which use the vacuum generated by suitable aspirators, compressors or vacuum pumps combined with suckers.
Questi metodi prevedono un inconveniente intrinseco: il contatto tra manipolatore ed uova à ̈ inevitabile, in particolare il contatto tra uova e ventosa, per esempio, durante il trasporto delle uova. These methods have an intrinsic drawback: the contact between the manipulator and the eggs is inevitable, in particular the contact between the eggs and the sucker, for example, during the transport of the eggs.
Nel caso di uova fessurate o parzialmente rotte, il contenuto dell’uovo viene aspirato dal sistema del vuoto, e questo richiede frequenti pulizie. Inoltre il contenuto dell’uovo rotto può entrare in contatto con le uova trattate nel ciclo successivo della ventosa, sporcandole ed eventualmente contaminandole in modo non accettabile per un prodotto destinato alla vendita. Si pone perciò innanzitutto un problema di igiene, ed in second’ ordine, di funzionalità ed efficacia del macchinario manipolatore. In the case of cracked or partially broken eggs, the contents of the egg are sucked up by the vacuum system, and this requires frequent cleaning. Furthermore, the contents of the broken egg can come into contact with the eggs treated in the next cycle of the suction cup, dirtying them and possibly contaminating them in a way that is not acceptable for a product destined for sale. Therefore, first of all there is a problem of hygiene, and secondly, of functionality and effectiveness of the manipulator machinery.
Scopo della presente invenzione à ̈ quello di ovviare agli inconvenienti anzidetti, proponendo un apparato per la manipolazione di uova molto semplice e con migliori caratteristiche di igiene e di costo rispetto allo stato della tecnica. The purpose of the present invention is to obviate the aforementioned drawbacks by proposing a very simple apparatus for handling eggs with better hygiene and cost characteristics than the state of the art.
In accordo con l’invenzione tale scopo à ̈ raggiunto con un manipolatore a testa aspirante per uova o prodotti fragili similari, caratterizzato dal fatto di comprendere un manicotto di presa dell’uovo, mezzi di alimentazione di aria compressa all’intemo di detto manicotto, una bocchetta di detto manicotto impegnatale con la superficie dell’uovo per la presa dello stesso e la fuoriuscita dell’aria da detto manicotto e mezzi per creare un vortice depressionario all’intemo di detto manicotto. In accordance with the invention, this purpose is achieved with a manipulator with a suction head for eggs or similar fragile products, characterized by the fact that it comprises an egg gripping sleeve, means for feeding compressed air inside said sleeve, a nozzle of said sleeve engages it with the surface of the egg for gripping the same and the escape of the air from said sleeve and means for creating a vacuum vortex inside said sleeve.
Queste ed altre caratteristiche della presente invenzione saranno rese evidenti dalla seguente descrizione dettagliata di un suo esempio di realizzazione pratica illustrato a titolo non limitativo negli uniti disegni, in cui: These and other characteristics of the present invention will be made evident by the following detailed description of an example of a practical embodiment thereof illustrated by way of non-limiting purposes in the accompanying drawings, in which:
la figura 1 mostra una vista in sezione verticale di un manipolatore per uova a testa aspirante secondo l’invenzione; Figure 1 shows a vertical sectional view of a suction head egg manipulator according to the invention;
la figura 2 mostra una vista in sezione secondo la linea II-II di figura 1. Figure 2 shows a sectional view along the line II-II of Figure 1.
Nei disegni à ̈ mostrata una testa aspirante 1 comprendente un supporto 11, un canotto fisso 10 ad asse verticale vincolato al supporto 11 ed un manicotto 22 montato in modo assialmente scorrevole sul canotto fisso 10 e sollecitato contro uno spallamento di battuta 24 dello stesso da una molla elicoidale cilindrica 23 reagente tra il supporto 11 ed un bordo 32 del manicotto 22. The drawings show a suction head 1 comprising a support 11, a fixed sleeve 10 with a vertical axis constrained to the support 11 and a sleeve 22 mounted in an axially sliding manner on the fixed sleeve 10 and pressed against an abutment shoulder 24 of the same by a cylindrical helical spring 23 reacting between the support 11 and an edge 32 of the sleeve 22.
Il canotto fisso 10 ha una camera interna 12 aumentabile con aria compressa tramite un foro di entrata 13. Il manicotto mobile 22 ha a sua volta una camera interna 26 ed una bocchetta conica 25. The fixed sleeve 10 has an internal chamber 12 which can be increased with compressed air through an inlet hole 13. The mobile sleeve 22 in turn has an internal chamber 26 and a conical opening 25.
Le due camere interne 12 e 26 comunicano tra loro tramite forellini 19-20 ricavati in una flangetta 18 unita al canotto 10 mediante viti 17. I suddetti forellini 19, 20 sfociano in una cavità conica anulare 14, sovrastante la camera 26, definita tra un cono centrale 15 e fianchi laterali 16 della parte inferiore della flangetta 18. Come mostrato in figura 2, i forellini 19, 20 sono paralleli ma spostati lateralmente da parti opposte rispetto all’asse verticale del cono centrale 15. The two internal chambers 12 and 26 communicate with each other by means of small holes 19-20 obtained in a flange 18 joined to the sleeve 10 by means of screws 17. The aforementioned small holes 19, 20 lead into an annular conical cavity 14, above the chamber 26, defined between a central cone 15 and lateral sides 16 of the lower part of the flange 18. As shown in figure 2, the small holes 19, 20 are parallel but displaced laterally on opposite sides with respect to the vertical axis of the central cone 15.
Per operare il prelievo di un uovo 28 viene alimentata aria compressa nella camera 12 attraverso il foro di entrata 13. Attraverso i forellini 19-20 l’aria compressa passa nella cavità anulare 14 della camera 26, generando grazie alle direzioni opposte dei forellini 19-20 un vortice depressionario 31 che risucchia l’uovo sottostante verso la bocchetta conica 25 del manicotto 22. To take an egg 28, compressed air is fed into chamber 12 through the inlet hole 13. Through the small holes 19-20 the compressed air passes into the annular cavity 14 of the chamber 26, generating thanks to the opposite directions of the small holes 19 -20 a depression vortex 31 which sucks the egg underneath towards the conical opening 25 of the sleeve 22.
L’aria compressa fuoriesce intanto dalla bocchetta 25 mediante flussi d’aria 29, 30 (fig. 1), che evitano il contatto tra l’uovo e la bocchetta. In the meantime, the compressed air escapes from the nozzle 25 by means of air flows 29, 30 (fig. 1), which avoid contact between the egg and the nozzle.
Le diverse altezze dell’uovo vengono compensate dalla possibilità di movimento assiale del manicotto 22, che si alza e si abbassa sotto la spinta della molla 23. The different heights of the egg are compensated by the possibility of axial movement of the sleeve 22, which rises and falls under the thrust of the spring 23.
Il manipolatore a testa aspirante secondo l’invenzione offre molti vantaggi rispetti agli apparati secondo la tecnica nota. The suction head manipulator according to the invention offers many advantages compared to the apparatuses according to the known art.
In primo luogo à ̈ assicurata la massima igiene. La testa aspirante non si sporca perché l’aria compressa, continuando a fuoriuscire, mantiene l’interno della stessa pulito. E’ così drasticamente ridotta la contaminazione da un uovo al successivo. First of all, maximum hygiene is ensured. The suction head does not get dirty because the compressed air, continuing to escape, keeps the inside of the same clean. Contamination from one egg to the next is thus drastically reduced.
La testa non aspira il liquido dall’uovo se non espellendolo immediatamente assieme all’aria compressa dalla bocchetta conica 25. Di conseguenza, la testa non necessita di pulizie e lavaggi continui come avviene negli attuali sistemi a ventosa. E’ possibile sollevare uova parzialmente rotte senza aspirare il liquido contenuto, ottenendo un recupero di prodotto. The head does not suck the liquid from the egg if not immediately expelling it together with the compressed air from the conical nozzle 25. Consequently, the head does not require continuous cleaning and washing as occurs in current suction cup systems. It is possible to lift partially broken eggs without aspirating the liquid contained, obtaining product recovery.
Non esiste alcun contatto diretto tra l’uovo e la bocchetta 25 del manicotto di presa 22. There is no direct contact between the egg and the mouth 25 of the gripping sleeve 22.
La presa e il distacco dell’uovo dalla testa sono più veloci. The taking and detachment of the egg from the head are faster.
E’ possibile utilizzare il manipolatore per qualsiasi prodotto alimentare. It is possible to use the manipulator for any food product.
Viene utilizzata soltanto aria compressa, che può essere filtrata e depurata da eventuali sostanze nocive. Only compressed air is used, which can be filtered and purified of any harmful substances.
Sono eliminate le pompe del vuoto e le valvole di inversione finora utilizzate. The vacuum pumps and reversing valves previously used are eliminated.
