DESCRIZIONE DESCRIPTION

Allo “Stato anteriore della tecnica” il taglio anche automatico di tubi di cartone e di plastica avveniva tramite un sistema di taglio che prevedeva un moto di avanzamento radiale posseduto dai coltelli ed un moto di taglio affidato al tubolare da tagliare che, ruotando su se stesso, consentiva il taglio a contatto con i coltelli. In the "prior state of the art", the automatic cutting of cardboard and plastic tubes was carried out by means of a cutting system that provided for a radial advancement motion possessed by the knives and a cutting motion entrusted to the tubular to be cut which, rotating on itself , allowed cutting in contact with knives.

La necessità di far ruotare il tubolare durante l’operazione di taglio rendeva necessario che esso fosse di buona qualità e soprattutto fosse sufficientemente circolare in quanto eventuali difetti di circolarità potevano poi essere causa di tagli irregolari, sfrangiati e comunque non idonei per il successivo utilizzo previsto. The need to rotate the tubular during the cutting operation made it necessary for it to be of good quality and above all to be sufficiently circular as any circularity defects could then be the cause of irregular cuts, frayed and in any case unsuitable for the subsequent intended use. .

Obiettivo che l’Invenzione Industriale dal Titolo: “Sistema di taglio automatico per tubi di cartone e di plastica con impostazione della misura di taglio e prelievo automatico dal magazzino con scelta del formato velocità nel cambio formato.” intende raggiungere è quello consentire il taglio di tubi di cartone e di plastica anche non perfettamente circolari e, comunque, con minori esigenze di precisione nella loro configurazione geometrica riducendo, inoltre, l’intervento dell’operatore, effettuata la programmazione della macchina, al solo caricamento periodico del magazzino contenente il materiale in lavorazione ed alla rimozione, anch’essa periodica, del prodotto finito e del pochissimo materiale residuo di scarto. Objective that the Industrial Invention entitled: "Automatic cutting system for cardboard and plastic tubes with setting of the cutting size and automatic withdrawal from the warehouse with choice of speed format in format change." aims to achieve is to allow the cutting of cardboard and plastic tubes even if not perfectly circular and, in any case, with less precision requirements in their geometric configuration, also reducing the intervention of the operator, once the machine has been programmed, only periodic loading of the warehouse containing the material being processed and the removal, also periodic, of the finished product and of the very little residual waste material.

Il “Sistema di taglio automatico per tubi di cartone e di plastica con impostazione della misura di taglio e prelievo automatico dal magazzino con scelta del formato velocità nel cambio formato.” è composto principalmente da: The "Automatic cutting system for cardboard and plastic tubes with setting of the cutting size and automatic withdrawal from the warehouse with choice of format speed in format change." is mainly composed of:

1. Un magazzino (Vedi Disegno 1 pari. 1) per il deposito del materiale in lavorazione costituito da tubi di cartone o di materiale plastico. La composizione dei tubi nel magazzino può anche essere frazionata, cioè vi possono essere depositati contemporaneamente tubi di tipo diverso, sia come dimensione che come materiale, posizionati separatamente all’interno di uno stesso magazzino e prelevati automaticamente in base alla programmazione effettuata. 1. A warehouse (See Drawing 1 par. 1) for the storage of the material being processed consisting of cardboard or plastic tubes. The composition of the tubes in the warehouse can also be divided, that is, tubes of different types can be deposited at the same time, both in size and material, positioned separately within the same warehouse and automatically picked up according to the programming carried out.

Sono previsti anche diversi magazzini intercambiabili fra di loro, contenenti materiale da lavorare diverso, come tipo di materiale e/o come dimensioni, oppure appartenenti a magazzini differenti ma intercambiabili fra di loro, manualmente o automaticamente. Various interchangeable magazines are also provided, containing different material to be processed, such as type of material and / or dimensions, or belonging to different but interchangeable magazines, manually or automatically.

2. Un sistema di deposito automatico del tubo in lavorazione (Vedi Disegno 1) su una guida a V che può avvenire sia dall’alto per gravità (Vedi Disegno 2 part. 1) che dal basso con azionamento pneumatico o elettro-meccanico tramite dei posizionatori del tubo che Io prelevano dal magazzino e lo depositano nella guida a V. 2. An automatic deposit system of the pipe being processed (See Drawing 1) on a V-guide which can take place either from above by gravity (See Drawing 2 part. 1) or from below with pneumatic or electro-mechanical activation by means of tube positioners that I take from the warehouse and deposit it in the V-guide.

3. Un sistema di traslazione del tubo in lavorazione sulla guida a V verso la zona di lavorazione-tranciatura di tipo semi-continuo (Vedi Disegno 2) tramite uno spintore passo-passo (Vedi Disegno 2 Part. 2 e Part. 3. A semi-continuous translation system of the tube being processed on the V-guide towards the machining-blanking area (See Drawing 2) by means of a step-by-step pusher (See Drawing 2 Part. 2 and Part.

3) che al termine della lavorazione di tranciatura del tubo (Vedi Disegno 2 Part. 4) ritorna indietro nella posizione iniziale, consentendo il caricamento del nuovo tubo, che verrà spinto passo-passo verso il taglio ripetendo il ciclo. 3) which at the end of the tube blanking process (See Drawing 2 Part. 4) returns back to the initial position, allowing the loading of the new tube, which will be pushed step by step towards the cut repeating the cycle.

4. Un sistema di traslazione di scorrimento del tubo sulla guida a V verso la zona di lavorazione-tranciatura di tipo continuo (Vedi Disegno 3) tramite un trascinatore (Vedi Disegno 3 Part. 1) montato in prossimità del giunto rotante (Vedi Disegno 3 Part. 2 e Disegno 1 Part. 2), nella zona prossima alla tranciatura che, al termine dell’ultima lavorazione di tranciatura del tubo in lavorazione, consente la caduta deH’ultimo pezzetto di tubo rimasto troppo piccolo per poter essere utilizzato (Vedi Disegno 3 Part. 3) ed il posizionamento del nuovo tubo (Vedi Disegno 3 Part. 4) lavorando così in continuo. 4. A tube sliding translation system on the V guide towards the machining-blanking area of continuous type (See Drawing 3) by means of a driver (See Drawing 3 Part. 1) mounted near the rotating joint (See Drawing 3 Part. 2 and Drawing 1 Part. 2), in the area close to the blanking which, at the end of the last blanking process of the pipe being processed, allows the fall of the last piece of pipe left too small to be used (See Drawing 3 Part. 3) and the positioning of the new tube (See Drawing 3 Part. 4) thus working continuously.

5. Un tampone maschio (Vedi Disegno 1 Part. 3 e Disegno 4 Part. 1), che, durante l’avanzamento del tubo, penetra dentro il tubo medesimo e funge da contrasto per i coltelli durante la fase di taglio. 5. A male plug (See Drawing 1 Part. 3 and Drawing 4 Part. 1), which, during the advancement of the tube, penetrates into the tube itself and acts as a contrast for the knives during the cutting phase.

A taglio avvenuto l’avanzamento del tubo causa lo scorrimento per spinta del materiale tagliato lungo il tubolare di supporto del tampone maschio di contrasto (Vedi Disegno 4 Part. 2) che funge così da serbatoio per il deposito temporaneo del prodotto tranciato e finito. Once the cut has been made, the advancement of the tube causes the cut material to slide by thrust along the support tube of the male contrast pad (See Drawing 4 Part. 2) which thus acts as a reservoir for the temporary storage of the cut and finished product.

6. Quando il caricamento del prodotto finito depositato sul tubolare porta tampone maschio è completato, un apposito comando pneumatico fa indietreggiare il tubolare medesimo (Vedi Disegno 4 Part. 3) determinando la caduta del prodotto finito, su di esso precedentemente raccolto, grazie ad una battuta (Vedi Disegno 4 Part. 4) che ne causa, appunto, lo sfilamento. Il prodotto finito cade su un apposito contenitore del prodotto finito che verrà rimosso periodicamente dall’operatore. 6. When the loading of the finished product deposited on the male pad holder tube is completed, a special pneumatic control makes the tube backwards (See Drawing 4 Part. 3) causing the finished product to fall, previously collected on it, thanks to a stop (See Drawing 4 Part. 4) which causes it to slip out. The finished product falls on a special container of the finished product which will be periodically removed by the operator.

L’ultimo piccolo spezzone di tubo, scarto dell’ultima operazione di tranciatura di dimensione non più utilizzabile, viene fatto cadere dall’avanzamento del nuovo tubo in lavorazione e viene raccolto in un apposito contenitore dello scarto che verrà rimosso anch’esso periodicamente dall’operatore. The last small piece of pipe, waste from the last blanking operation of a size that is no longer usable, is dropped by the advancement of the new pipe being processed and is collected in a special waste container which will also be periodically removed from the operator.

7. Il sistema di taglio è composto da due coltelli costituiti da due dischi folli (Vedi Disegno 5 Part. 1) montati al 80° l’uno rispetto altro su un giunto rotante (Vedi Disegno 5 Part. 2) provvisto di un comando pneumatico per la loro traslazione radiale. 7. The cutting system consists of two knives consisting of two idle discs (See Drawing 5 Part. 1) mounted at 80 ° with respect to each other on a rotating joint (See Drawing 5 Part. 2) equipped with a pneumatic control for their radial translation.

Il comando pneumatico fa traslare i due coltelli (Vedi Disegno 5 Part. 3) , posti l’uno di fronte all’altro a 180° , in direzione radiale fino a portarli a contatto con il tubo da tagliare (Vedi Disegno 5 Part. 4). The pneumatic control moves the two blades (See Drawing 5 Part. 3), placed one in front of the other at 180 °, in a radial direction until they come into contact with the pipe to be cut (See Drawing 5 Part. 4 ).

A contatto coltelli-tubolare avvenuto il giunto rotante (Vedi Disegno 5 Part. Once the knives-tubular contact has occurred, the rotating joint (See Drawing 5 Part.

4) compie una rotazione maggiore di 180° trascinando i coltelli ad esso collegati che, continuando ad avanzare radialmente per effetto del comando pneumatico, causano il taglio del tubo con il tampone che funge da contrasto all’interno del tubo medesimo. 4) performs a rotation greater than 180 ° by dragging the knives connected to it which, continuing to advance radially due to the pneumatic control, cause the tube to be cut with the pad that acts as a contrast inside the tube itself.

A taglio effettuato il comando pneumatico richiama in posizione esterna i due coltelli ed il giunto rotante riprende la sua posizione originale effettuando una rotazione di senso opposto rispetto alla precedente. Once the cut has been made, the pneumatic control brings the two knives back to the external position and the rotating joint resumes its original position by performing a rotation in the opposite direction compared to the previous one.

Il comando di avanzamento radiale dei due coltelli a disco può essere effettuato anche tramite un motore passo-passo al fine di ottenere un valore più preciso della loro corsa con conseguente certezza di non danneggiare il tampone maschio che funge da contrasto per il taglio e che si trova all’interno del tubo in lavorazione. The radial advancement command of the two disc knives can also be carried out by means of a stepping motor in order to obtain a more precise value of their stroke with consequent certainty of not damaging the male plug which acts as a contrast for the cut and that located inside the tube being processed.
